It's an enforcement of individual decision, not a decision replacing users' ones. If I want to use Facebook to some extent but stop them from selling all my data to everyone, I may need something more than just their word to make sure they respect my decision.

This is an unrealistic expectation. You signed a legal contract when you signed up for an account stating that you're a-okay with them using your data.
The last time I logged in, I found that the following have uploaded information about me to Facebook’s ad targeter:
* my car’s manufacturer
* charities I donated to
* political campaigns (red and blue)
* some of my banks
* random pop music groups I have never heard of (thanks, spotify(?))
* my preferred pizza delivery company
and at least three dozen others.
As far as I can tell, this behavior will soon be illegal in Europe.
