>I think it's not properly appreciated that Apple fully endorses all of this. [...] they uniquely could stop this (at the price of devastating their app store), but choose not to.
A perfectly privacy respecting app store isn't going to do any good if it doesn't have any apps. Just look at f-droid. Most (all?) of the apps there might be privacy respecting, but good luck getting any of the popular apps (eg. facebook, tiktok, google maps) on there.
>In light of that, perhaps reevaluate their ATT efforts as far less about meaningful privacy and far more about stealing $10B a year or so from Facebook.
What would make you think Apple's pro-privacy changes aren't "about stealing $10B a year or so from Facebook"? At least some people are willing to pay for more privacy, and pro-changes hurts advertisers, so basically any pro-privacy change can be construed as "less about meaningful privacy and far more about stealing".
