If you want a negative example, check out Voat. It started as a "less moderated/censored reddit" and quickly filled with actual nazis and other vitriol. A business cannot survive on "We accept hate speech" in the same way 4chan has never really been a business proposition; Nobody wants to look like they are supporting hate speech so advertisers won't go near it with a ten foot pole.
IMO, this is a good thing, and implies there is at least some decency in the world
