And they were tracking even non-Facebook users this way. There's zero consent here no matter how you cut it.

Worse yet, Facebook did this for years, and in the first years it swore it doesn't do that, and when they were caught doing it they said it was "just a bug"...twice.

Facebook has 0% credibility at this point. Just look how they're ruining people's trust in 2FA security, too, now (although if they end-up ruining the trust in SMS 2FA, that wouldn't be too bad of an outcome actually...).

This is a good article (although not complete, and only until 2014) on Facebook's awful, no-good, history of lying and tracking users without their consent:
