I wouldn't be surprised if this is on purpose.

If you have a law which is impossible to comply with, and are allowed to selectively enforce that law, you can (within limits) force anyone to implement any policy of your own choosing, with 0 public oversight.

The EU probably couldn't pass a law requiring Meta to remove opinions critical of EU politicians. It would generate too much (justified) social outrage and anger human rights / free speech activists. What they can do is to have an entirely unrelated law, which Meta must break to operate. They can then secretly use the treat of enforcing that law to make Meta implement the policies they want, voluntarily and of their own free will.

I'm not saying this is the specific company / policy combination this will be used for, but it's probably going to be something of that nature.

It's a mess, and it's not the first time the EU is doing this.

The GDPR is ripe with such abuses. Basically nobody (including European companies) fully complies with it, and the EU chooses who they don't like and who they wish to prosecute.
