"the fact that FB knew about it and did nothing" is unsubstantiated. The person I trust the most on this is Alex Stamos, who actually left Facebook due to tensions over this, and he's gone on record saying there was no obstruction.
> 2. FB running psychological experiments in the newsfeed not only to see if they can make you spend more time there (questionably ok) but also to see if they could affect your mood (definitely not ok).
From 2014. I'd also disagree with running A/B tests to increase time spent being "questionably ok" though.

3. Facebook censoring news in the newsfeed based on political leanings.
I can't find anything online about this? Unless you're talking about filter bubbles, in which case I think that's a reasonable criticism although I think describing it as "censorship" is a huge stretch.
4. FB tracking you even after you log out.
Again, from 2013.

5. Zuck lying on capital hill about what he knew and when.
Can't find any news articles about this.
6. FB hiring a pr firm to right negative articles about an investor.
Fair criticism.
