@matigo I'm not so sure it's better, since in most of these systems, ultimately "someone else" is responsible for the platform. That "someone else" is perhaps more visible than on, say, Twitter or Facebook, and there may be a bit more transparency about decisions as a result, but they can also be bullied by the mob.
In an ideal world, these systems would be entirely distributed and only the end user could make a decision about what they will and will not see. Any "censorship" decision, in this case, would only affect one individual.
