it is very difficult to figure out what specific effect ATT has because there are so many factors involved

If ATT were so significantly kneecapping revenue, I would think we would see a pronounced skew against North America compared to elsewhere. But that is not the case. Revenue in North America is only slightly off compared to the company total, and it is increasing how much it earns per North American user compared to the rest of the world.

iOS is far more popular in the U.S. and Canada than it is in Europe, but Meta incurred a greater revenue decline — in absolute terms and, especially, in percentage terms — in Europe. Meta was still posting year-over-year gains in both those regions until this most recent quarter, even though ATT rolled out over a year ago.

there are those who believe highly-targeted advertisements are a fair trade-off because they offer businesses a more accurate means of finding their customers, and the behavioural data collected from all of us is valuable only in the aggregate. That is, as I understand it, the view of analysts like Seufert, Benedict Evans, and Ben Thompson. Frequent readers will not be surprised to know I disagree with this premise. Regardless of how many user agreements we sign and privacy policies we read, we cannot know the full extent of the data economy. Personal information about us is being collected, shared, combined, and repackaged. It may only be profitable in aggregate, but it is useful with finer granularity, so it is unsurprising that it is indefinitely warehoused in detail.

Seufert asked, rhetorically, “what happens when ads aren’t personalized?”, answering “digital ads resemble TV ads: jarring distractions from core content experience. Non-personalized is another way of saying irrelevant, or at best, randomly relevant.”

does it make sense to build the internet’s economy on the backs of a few hundred brokers none of us have heard of, trading and merging our personal information in the hope of generating a slightly better click-through rate?

Then there is the much bigger question of whether people should even be able to opt into such widespread tracking. We simply cannot be informed consumers in every aspect of our lives, and we cannot foresee how this information will be used and abused in the full extent of time. It sounds boring, but what is so wrong with requiring data minimization at every turn, permitting only the most relevant personal data to be collected, and restricting the ability for this information to be shared or combined?

Does ATT really “[deprive] consumers of widespread ad relevancy and advertisers and publishers of commercial opportunity”? Even if it does — which I doubt — has that commercial opportunity really existed with meaningful consumer awareness and choice? Or is this entire market illegitimate, artificially inflated by our inability to avoid becoming its subjects?

Conflicts like these are one of many reasons why privacy rights should be established by regulators, not individual companies. Privacy must not be a luxury good, or something you opt into, and it should not be a radical position to say so. We all value different degrees of privacy, but it should not be possible for businesses to be built on whether we have rights at all. The digital economy should not be built on such rickety and obviously flawed foundations.
