At what price, tho? He harms children, he hijacked the attention of billions and helped the rise of facism and hate, which if not addressed will lead into very dark times again, all for a measly 3% out perform?
If the rise of fascism and hate is due to people being able to talk to each other on Facebook with insufficient censorship, it seems your actual problem is the system of governance that gives everyone a right to vote, even if they do it based on some nonsense they read online.
There's also the allegation that a) Facebook greatly overcounted (on purpose) the impressions from autoplaying videos and b) their ads target more people in an area than physically exist
"Value" is a tough thing to translate. Market cap, and whatever. Considering the fact so many people express difficulty in deleting their accounts - it won't let you, or it gets reactivated later - I'm just going to state the quiet part out loud here; Facebook's valuation is mostly or entirely fraud
