People install extensions that have access to things like "all data on Facebook.com" far too easily from complete strangers on the internet :/
Why would you trust your Facebook account (or any other account) to a random stranger on the internet you've never met, heard of, or even seen? Whose real name you probably don't even know?
It's worth nothing that everyone who works at Facebook, including the CEO, are random strangers. That I know (some of) their names doesn't help me sleep well at night.
Incidentally, I don't have a facebook account, and I sleep fine.
Edit: didn't Mark Zuckerberg once say "people who trust me are dumb fucks", or something to that affect? Screw that guy and the horse he rode in on.
Now if his behavior was consistent and he continued to say things like that today, then maybe the evidence would hold some merit. Otherwise it's just pointless cherrypicking. To hold something like that against him over a decade later? That's just irrational hatred.
And just to be clear this is the full quote with context: https://pastebin.com/4a2aLp11
And with the extra context, the quote makes more sense. At the time it was dumb of those people to just submit personal information to a random dude at Harvard.
There is a big difference between a multi-billion dollar company that has a reputation, shareholders etc. and a completely random person (who could literally be anyone with any motives). You can't go to Facebook and give them an envelope of cash for keys to access other peoples Facebook accounts whereas some random guy is much more likely to be open to this.
Security online is already shit and people freely handing out access to their online accounts is not making things better. There's need to breach servers anymore, you just create a "fun" browser extension with god permissions that auto-updates and then after a few weeks just start harvesting usernames, passwords, card details, instant messages and emails... :/
