The Google/Facebook, etc position is that they should decide what user PII they collect and how they use it. Your position is that it's ok for Apple to decide what user data can be collected and how it's used ("What's wrong with banning?").

But there is a third party here who's opinion is the one that actually matters. If you considered their existence and role here for even a second, the reason why it would be wrong for Apple to decide with a direct ban would be immediately obvious - that third party is the users.

My position, and that of Apple, is that it's none of Apple's business, and it's none of Google/Facebooks business to decide these things. It's the user's business how their data is used, they should be making these decisions. That's why it would be wrong for Apple to impose a ban.

After all the Google/Facebook narrative is that their use of PII brings value to users in the from of relevant ads and personalised services. Well ok, make that case to users and let them decide.

I've been banging on about this through the whole comment thread, but you just seem flat out unable to even see that users have any role at all in this. You ignore their existence and role implicitly without the slightest consideration; their right to choose is _the_ consideration here. It's not some incidental, inconvenient factor to be dismissed as a 'de facto' input to be taken for granted so you can point the finger unerringly at Apple.
