The problem with Facebook is that they track everyone, FB users or not. Most likely breaking GDPR for basically every European who uses the internet.

Good talk from a few weeks ago: https://media.ccc.de/v/35c3-9941-how_facebook_tracks_you_on_...

(that's just android, but they do just as much web tracking through their pixel for example).

Agreed, it's a way over the top. However, I would like the EU, or the US, to tell Facebook to get their data collection and reselling under control. The GDPR should have taken care of that issue, but until someone drag Facebook to count over a GDPR violation and wins, nothing is going to change.
