2. Apple's new privacy changes require that apps solicit user permission before doing any tracking. However, once the user has granted that, app developers are allowed to either use Apple's solution or their own.
Apple's AppTrackingTransparency Framework harms a market that Apple is not a part of. That specific action doesn't have any monopoly connotations in my mind because it solely benefited the product that was changed. There are no knock on effects where now Apple Maps is worth more.
Also, in this case, the consumers that are harmed by Google's alleged monopoly are people who are buying ads, not people using Chrome. I don't do anything with ads, but the impression I got from other people is that it's much easier for a consumer to switch phones than it is for an advertiser to just not advertise with Google.
I do think Apple has monopoly issues, I just don't think ATT is part of it. That was a legitimate response to consumer demand for privacy.
The most generous thing I could say is that it feels different. However, Apple has a stronger hold on iOS than Google has on the web. On the web, at least you could switch to another browser to view the same content. Switching off iPhone requires a whole new ecosystem and hardware.
I hope people who argue for a certain treatment of Google in this case are at least consistent in the Apple case.
