I'd rather have appalling speech than censored speech. The idea is to not confuse supporting a person's free speech with endorsing his views. Also, reddit is a private company and so is not obliged to provide a platform for anyone's free speech, that also is a facet of freedom.
Free speech is between you and the government. If a company that runs a forum says it bans people for abusive comments there's nothing to do with free speech. We see with Reddit that the ugliest users are the ones that are the loudest and drown out everyone else.
No. Free speech is a principle that any party can choose to respect. Free speech has been one of the very core values of Reddit right from the beginning, in the form of the ability to create and manage a subreddit with very minimal restrictions.
Being a platform of free speech was the single biggest reason Reddit grew to be the giant community that it is today.
Then Pao comes along and repeatedly shows that she doesn't respect free speech at all. What do you expect the users to do, other than revolt?
It's easy to brush off these incidents as the doings of "the ugliest users", but remember that beauty is in the eye of the beholder. History books are filled with people being silenced due to their expression of uncomfortable ideas.
