I think they'd be happier with the policy of, "if you don't like it, leave" than trying to appease others.
Also people need to realize chan culture. Each board may as well be its own website. 4chan hosts /pol/, it also hosts /lgbt/. 4chan's moderation (rather, lack of) is being seen as an issue because of how heavily moderated the internet has become in the past 20 years.
Reddit, the "bastion of free speech", bans every subreddit that gets in the way of advertisement money, giving Voat more popularity. 4chan, "a bastion of free speech", banned #Gamergate discussion which gave 8chan its rise to popularity.
I'd rather have extremists on Reddit and 4chan where they can be debated and talked down to by moderates than on Voat and 8chan where they can form echo chambers. Echo chambers are a lot better at recruitment. Pushing "bad people" away where they are out of sight and out of mind hasn't been solving the problem, it has only been making it worse year over year.
if you are old enough to remember /b/ raiding Hal Turner, i'm pretty sure that same thing would have happened to Alex Jones had raiding not been banned.
