The fb webpage still exists. No app. No permissions. No problems.

If Facebook makes a change that kills the low-tracking front-ends and insists everyone be tracked more, and in response you grovel to them and put up with their new app, then no amount of EU law or App store law was ever going to protect you from yourself. Apple store polices are a red herring, the problem you're actually highlighting is the adversarial relation you have with fb.
