The people who cry about censorship on big platforms are people who want to access the audience. They aren't crying for the censorship itself (they usually love when people with opposing views get banned), they are just using that word to complain about them losing an audience. Setting up a personal website doesn't meet that goal, and probably a thing like this doesn't either. Most of the nazis etc. are quite miserable in their "censorship-free" platforms, because they can't reach normal people there.
