> I have a feeling they will allow that as otherwise Facebook's predatory business model will make no sense until they find a way to trick users into consent

Luckily European courts don't really give a damn about Facebook or their business model.

It's not that European courts never play favorites with large companies, but Facebook isn't really known for paying a lot of taxes here and doesn't have many employees in Europe (at least an order of magnitude less than e.g. Volkswagen). Facebook is seen as a foreign company that doesn't know how to play by the rules, and was a major motivation for creating the GDPR in the first place.
