Every platform censors to at least some degree or they wouldn't continue existing as a platform. What matters to most folks is the degree of censorship. As YouTube is beholden to advertisers, it's kind of akin to cable TV in terms of what will and won't be shown.
You can have a fairly minimal degree of censorship limited to actual criminal speech. There's no reason why platforms can't adopt that as their standard.
