It is merely a tool, guided by the same principle Aaron Swartz implanted into reddit. Freedom of choice, freedom of expression, as long as the laws in the country hosting the servers are upheld. Communities can form and moderate the content as they please, but alternative communities can also form with perhaps less moderation. It is up to the users to make it what they want, not funded by advertizing, but rather with potential donations. It doesn’t have to be huge. If it gets too big, it should be able to split up.
