Have you ever felt like you are standing on a ship where every time you look out at the sea, you see a new storm approaching? That is precisely how thousands of publishers and advertisers worldwide have felt over the past few days as Apple continues to show that it has no intention of stopping its fight against user tracking.
Let's go back to mid-September 2026. Apple quietly released the iOS 27 update for Safari. There was no prior announcement. No press conference. No opportunity for the advertising industry to prepare. Simply put: Safari for millions of iPhone and iPad users worldwide began to stop communicating with a list of advertising companies known only to Apple.
Over the past week, the first damage statistics have started to be compiled. These numbers are not just dry lines of data. They tell a story of lost revenue, upended business plans, and an industry struggling to adapt to an unwanted new reality.
Initial Damage: Far from Small Numbers
Let's start with the actual data. Aditude, a platform that helps publishers sell their ad space, has published notable statistics regarding the impact of this update.
First, let's look at scale: Safari on iPhones and iPads accounts for 11.7% of the ad inventory displayed to Aditude's clients, and 11.4% of their ad revenue. This is no small figure. It represents a significant portion of any publisher's financial picture.
However, what is more concerning is the eCPM metric—the actual earnings per thousand ad impressions. For users who have installed the latest update, eCPMs have dropped by 10.5%. And this is just the beginning, as only about 8% of users have upgraded to iOS 27. Aditude estimates that the current total revenue impact is only about 1%—but that number will rise rapidly as more users update.
Pause for a moment to consider this. If eCPMs have dropped by more than 10% with just 8% of users updating, what will happen when that figure reaches 50%? Or 80%? Or when all iPhone and iPad users have updated?
Yet, not all publishers are feeling the immediate impact. Scott Messer, who runs the consulting firm Messer Media, noted that the publishers he advises "see little direct impact" from the block. Nevertheless, he predicts that will change as more users install the update.
Some publishers might even escape the worst impacts. Two senior commercial executives at news publishers told Digiday that they have not seen any fallout from the block and are unconcerned. One chief revenue officer (CRO) explained that this is primarily because they operate a business primarily driven by paid subscriptions, and do not worry about the impact of Apple's changes on their programmatic advertising.
This is a crucial point: publishers with diversified business models, especially those built on subscriptions, will be much less vulnerable than publishers entirely dependent on ad revenue.
History Repeats: When Apple Cost Billions
For those who have followed the digital advertising industry over the past decade, this story is not new. It feels like a play we have seen before, but this time with a potentially worse ending.
Recall back in 2017 when Apple first introduced Intelligent Tracking Prevention (ITP) in Safari. It was a shock to the advertising industry. Previously, ad companies could track users quite easily using third-party cookies. ITP changed all of that, impacting billions of dollars in revenue.
Then in 2021, Apple caused another stir by launching App Tracking Transparency (ATT). This feature required apps to ask users for permission before tracking them. The results were devastating. Meta—the parent company of Facebook—stated that ATT would cause them to lose approximately $10 billion in revenue in a single year.
And now, in 2026, Apple is following up with an even more aggressive measure. This time, they are not just restricting ad companies' tracking capabilities. They are completely blocking certain companies, preventing them from operating within Safari.
Notably, the list of blocked companies is not publicly disclosed. Only a select few insiders at Apple know who is on that list. For an industry accustomed to being surprised by Apple, this makes everything even more challenging.
Industry Reaction: Anxiety, Resentment, and Accusations
Unsurprisingly, the reaction from the advertising industry has been swift and strong. One publisher executive, speaking on the condition of anonymity, called the move a "blatant" attempt by Apple to give advertisers more incentive to use Apple's own ad network.
"Anything that makes advertising harder for advertisers in Safari will benefit Apple's own advertising business," this executive added. "It will harm publishers with lower levels of direct-sold inventory compared to established brands that monetize a significant portion of their inventory through direct-sold campaigns."
This is an extremely critical point. Smaller publishers who rely on programmatic advertising to make money will be hit much harder than large publishers with direct relationships with advertisers. In other words, this block will exacerbate inequality within the publishing industry.
Consultant Davide Rosamilia put the matter more bluntly: "The trend has definitely become more restrictive for anything that creates an identifier, especially on Apple. It's not going to get better. I would say it's going to get worse."
Furthermore, there is deep frustration within the industry regarding how Apple handles matters. Very few people have anyone to call at Apple. Apple rarely explains their changes before rolling them out, and when they do respond, they tend to keep things brief and on their own terms. One source, speaking anonymously, told Digiday that the IAB Tech Lab has long tried to reach out to Apple regarding their privacy policies without receiving a satisfactory response.
Why Is Apple Doing This?
To outsiders, this move may seem like part of the company's long-term strategy to position privacy as a competitive advantage. Apple has invested heavily in building an image as a technology company that protects user privacy better than anyone else.
However, many also believe this move is not solely about privacy. It is also about business interests. By making advertising more difficult for third-party companies within Safari, Apple indirectly encourages advertisers to use its own ad network, where it retains total control over data and user identifiers.
This is a sophisticated strategy: you are praised as a privacy hero while making more money from advertising. A perfect combination of public interest and business profit.
Nevertheless, an interesting detail has emerged: Apple asked The Trade Desk to test an iOS 27.2 build that could unblock ads. This suggests Apple may be reconsidering certain aspects of this move, or at least attempting to address industry concerns.
Strategic Response for Publishers and Advertisers
So, what should publishers and advertisers do in light of this situation? Here are practical strategies that I, with 20 years of experience in the industry, recommend considering:
1. Diversify Revenue Sources
The biggest lesson from Apple's previous policy shifts is: don't put all your eggs in one basket. If your revenue depends entirely on programmatic advertising, you are in a highly vulnerable position. Explore alternative revenue models such as paid subscriptions, content sponsorships, e-commerce, or value-added products and services.
2. Focus on First-Party Data
First-party data—information you collect directly from your customers—is becoming increasingly important. Invest in building your own customer database, ranging from newsletter signups to loyalty programs. This is an asset you own that no one can take away.
3. Explore Alternative Solutions
The IAB Tech Lab and other organizations have developed alternative solutions like Trusted Server. This is an architecture that gives publishers more control over their ad processes, reducing reliance on third-party companies. Learn about these solutions and evaluate whether they fit your business model.
4. Invest in High-Quality Content
In a world where behavioral targeting is increasingly difficult, high-quality content and contextual targeting will become paramount. If you create content that people genuinely want to read, you will attract a loyal audience, and those audiences will remain valuable to advertisers regardless of what Apple does.
5. Build Direct Partnerships with Advertisers
Publishers with direct relationships with advertisers will be less vulnerable than those relying solely on programmatic ads. Invest in your sales team and build relationships with brands looking to reach your audience.
When Privacy Becomes a Business War
I have witnessed the digital advertising industry go through many revolutions. From the days when we could track every user behavior to an era where privacy is the top priority. Each time, the industry has had to adapt and find new ways to survive.
Yet this time is different. This battle is not just about technology or regulation. It is about power. Apple is leveraging its dominant position in the mobile device market to reshape the entire digital advertising ecosystem. And they are doing so without anyone else's consent.
The concerning part is that publishers and advertisers are not the only ones affected. Consumers will also feel the impact. When publishers lose revenue, they will have to cut costs, including reducing newsroom staff and content quality. When advertisers cannot target effectively, they will have to pay more for each conversion, and those costs will be passed on to consumers.
Ultimately, we all pay the price for this change—one way or another.
Still, as I often tell my students: in every crisis lies an opportunity. Publishers and advertisers who can adapt the fastest, diversify their revenue sources, and build direct relationships with their audiences will be the winners in this new game.
The question posed to all of us is: Will you be the one who adapts or the one left behind?
What are your thoughts on Apple's latest move—is it a logical step forward to protect user privacy, or is it a business strategy disguised under the banner of privacy to reinforce Apple's monopoly in the ad market? If you are a publisher dependent on ad revenue, how will you adjust your strategy to survive in an era where platforms exercise tighter control over user data?
