content: It kind of already exists.  Freenet is an example.  The problem is it gets used almost solely by people who are into things most people don't like, so people write it off.  If you want to say something and not have it removed it's pretty easy.  If you want unredacted media then it is available. Just run it with a VPN though.  Some cops in Missuri came up with completely bogus way to "hack" it.  There method has a high false positive probability.  A judge who is technically illiterate didn't catch on and so warrents are issued literally to random freenet users.  Freenet though rather than http offers much less capacity for browser fingerprinting so a vpn actually does something effective for it.
