Interesting. It seems like after the senate hearings, Facebook is trying to communicate to its users that sending them your data is a necessary part of using their services.
That's what I would do: quit Europe. FB is part of life of millions of people. They would cancel this GDPR thing in a day to save their FB experience. Or at least add an exception to GDPR for FB.
For US & Canada this was $86.65 in the last 4 quarters.
For Europe this was $34.95.
Keep in mind they likely don't target ads using just one person's data: accuracy can be improved by looking at the data of similar people, and looking at the data of friends and family. It isn't as simple as offering a $10/month plan to keep your privacy, because they want everyone's data.
