Back when there was usenet, everybody could post what ever they wanted (some news servers might not have carried the group, but there was no policing the source).
Same with blogs: You wanted to post content the masses dislike? No problem. But you want to post that same content to a centralized platform like Twitter, Facebook or any of Google's properties, now the masses (and/or governments) dictate the content you are allowed to post.
To really make use of the internet's capability of providing an incredible freedom of content you can create and publish, you cannot use a centralized platform.
While sites like reddit or facebook might make it easier for other people to find your crap^Wcontent, they also make it infinitely easier to have it removed again.
