This type of quote is getting to be a version of that "everything digresses to calling people nazi" rule.

Anyway, you're presuming that people would have a choice

The only reason Facebook and Google are going to have to get permission to not track you on iOS is the App Store. If they could circumvent the App Store you bet they would and the first thing to go would be those pesky privacy protections.

I don't want to give my CC info to a half dozen different companies with worse data security records than Apple, but suddenly every app will require me to install another "App Store", so suddenly my choices become "share my info with dozens of companies that can sell it" vs "don't install any software"

That's such a great choice you've given me.
