I bet you a tenner Facebook immediately moves out of EU App Store and will be sideload only, with all privacy related permissions required for the app to run.
But you know what is reality and not FUD? App Stores pushing legal apps out, at least people in EU could have an option when this will continue to happen.
The Apple cartel protection-racket framing makes only sense in a market without privacy regulations, in the EU choice and privacy aren't mutually exclusive.
