It's not so much the security teams as it is the society-destroying beliefs of Facebook's upper management. Doesn't matter how good your security team is when they take marching orders from people who aren't aligned with improving society's health.
No one asks or expects that of you. The amount of negative press FB has managed to generate over the last few years, however, is more than enough to question the beliefs of FB managers.
No, it's not. You're basically just saying this is common knowledge, and as far as I can tell, common knowledge of how Facebook works internally is pretty poor.
And why would it be otherwise? People have read a lot of different articles of varying accuracy and there are also a lot of myth-making. There's no reason to believe average knowledge of Facebook is any more accurate than average knowledge of global warming or nutrition.
The details of internal Facebook procedures may be not known (though honestly, how secret can they be if most of the people in SV, for example, either know somebody who works for Facebook or somebody who used to work there?) but the public pronouncements and public actions of Facebook management can be readily observed. Nothing in these actions suggests Facebook as an organization values privacy, freedom of speech, thought diversity or robust public discourse.
