What you're describing are basically non-events in the history of bad decisions made at reddit (and like half of them come from Yishan's tenure, anyways). And reddit survived just fine every time, mind you.
There really wasn't anything overly egregious here except an angry internet mob. If it weren't for the subreddit blackout (which, again, was from an issue boiling over for years) timed so soon after the FPH shutdown I would give good odds it would have dissipated and we wouldn't be seeing this resignation today.
She was the CEO, she ultimately bore responsibility for every single decision made in her tenure. Regardless if initiatives were started under a previous CEO, she allowed bad decisions to be made public in her tenure where she had the power to stop them.
Like it or not, the CEO is ultimately responsible for every single thing a company does. That's pretty much their job.
Edit: Also, I have been on reddit for nearly 10 years. I've followed every stupid decision made since comments were implemented. I have never seen a period of bad decisions like this before Pao.
Edit 2: I also think it's sort of shitty for you to move the goalposts. You basically said "there's nothing else major" about Pao to criticize. As soon as I brought up three more things to criticize - well, they weren't important and everyone else is responsible.
