Can we please stop calling these privacy violations bugs? It sounds like a benign thing. These are not bugs anymore. It's unauthorized access to records of millions, and Facebook is the one who performed the violation. I can give a dog walker or cleaning personel the keys to my apartment, still if they steal stuff and I have evidence they will be prosecuted. It's not a bug that they don't have business ethics.
So a hacker took all of Equifax's data including your SSNs, address, names, DOB etc. By your analogy, all of Equifax engineers should be in jail right now! BTW, just in case you are unaware, Equifax got away with this hack with zero fines in US.
Most of the other Facebook data breaches where they didn't secure data accordingly would compare more to what you refer to.
This case is different though as Facebook performed unauthorized actions on email accounts, basically breaking in.
