Apple has been doing that for years:
- The iCloud Keychain API that lets Facebook, TikTok etc. track users across devices, app reinstalls and device resets.
- Ads in formerly ad-free built-in apps.
- Removing the Disable Javascript from Safari's menu so you can't easily disable the now-mandatory tracking bullshit on most sites.
- Ads
- "Force closing" apps on iOS not really force quitting them instantly anymore, giving each app a "last breath" chance to call home about anything it wants to send about you.
- Ads
- And now they've added nagging when you try to cancel recurring in-app subscriptions.
And I don't know enough about the keychain.
But removing the easy access button that breaks so many websites is not selling out users.
Giving an app some fraction of a second to clean up is not selling out users. This is a pretty ridiculous stretch on your part. If it had something to phone home it could have done it five seconds ago, why wait? Or it could probably do it the next time you open the app. That's not what the grace period is about.
