> The individual wasn't the one who truly decided the essential means and purposes beyond personal use

The user is supposed to have read Meta's terms and conditions and agreed to them. Of course nobody does that, but that doesn't absolve of the responsibility, it rather means that the user who uploads stuff to Meta does things in full knowledge and willingly or carelessly. It just might make Meta liable as well, because naturally their terms were sneaky, hidden, unclear and probably illegal.

And I'd guess that Meta Ireland has been sued often enough that they have some export clause deep in their conditions as well, which the user should also have read and agreed to.
