Have you considered the Occam's razor possibility that Europe genuinely doesn't want these companies doing business the way they do, rather than it being a conspiracy to increase government revenue? Remember, it's often illegal to take a photograph in public in Germany, and for this reason Google Street View is decades old.
I think if people of a country have a standard for how companies should act that's fair game. If they don't want companies to do that stuff than the companies leaving or crying isn't a bad thing, it's accomplishing the goal.
If I understood correctly, you think people genuinely wanting privacy, and preferring to have more privacy and no Facebook rather than less privacy and more Facebook, is inherently worse than actual corruption. This says more about you than about the EU.
This has nothing to do with Facebook or a specific entity. This is about accessing and capturing already available public data (e.g. someone's appearance in public).
Just like ad hominem framing tells more about you than me.
It is usually whatever company isn't friendly enough to the current government.
In Canada, it is any company that dares to compete with the telecom companies.
