To completely hijack the discussion here, I believe that Apple is actually one of the strongest forces for anti-privacy in the world, because of their long-term, successful push for the convention of app > website (not fully supporting PWAs, disallowing web push, etc). A website may spy on you, but it can only do so in ways constrained by the browser, which has to serve many "masters". Mobile apps are completely unconstrained in their spying, and in-app browsers are just the logical extension of that pattern.
Thanks largely to Apple, we've conditioned ourselves to expecting that you can't have good mobile UX without a mobile-native application, and it's hard to imagine ever escaping back into the relatively open web now that we're this far down this path. Most people will never question the privacy implications of installing the Facebook app, and most of Apple's privacy-directed efforts on iOS are basically playing walled-garden whack-a-mole on problems that are better solved at a societal level with web browser standards.
Yes, it's quite likely that I'm scapegoating here, but it's the way I see it.
