Whenever there is a big FB story I try and figure out what actually happened. This is often difficult because 95% of the media reporting on it is either entirely wrong, intentionally misleading, or both.
For the recent Cambridge Analytica thing my take away was that a shady third party (CA) violated FB’s TOS by exploiting a vulnerability in their API that FB had sinced locked down. Cambridge Analytica used that to pull more data from the social graph than they should have been allowed to (after a subset of users participated in scammy quizzes) in order to do stupid things with that data.
When I’ve read the rare detailed reporting from FB’s response [0] about how they’re reacting to issues I’ve been impressed.
Zuckerberg’s comments to the public are also pretty detailed and nuanced - atypically rare for a public facing CEO under massive persistent scrutiny.
This is consistent with what I’ve heard from my friends that work there.
