“The moral of the story is: if you’re against witch-hunts, and you promise to found your own little utopian community where witch-hunts will never happen, your new society will end up consisting of approximately three principled civil libertarians and seven zillion witches.”

The solution to that may be to separate the hosting from the discovery.

If the hosting is anonymous and censorship-resistant then you'll get every type of content, but for anybody to use it they would first have to find it.

Then you have a slew of independent discoverability portals. Some are created for child pornography, so the FBI hacks into them and then uses them to arrest everybody there. Others are created to replace Tumblr and YouTube and refuse to link to child pornography, so child pornographers have no reason to go there and the people disgusted by child pornography can safely use them.

But setting up a discoverability portal is a lot less expensive than setting up a hosting service (because a link uses much less bandwidth than high quality video), so there should be more competition, and in particular it should still be difficult to censor anything that has more than a modest amount of popular support.

This is what Freenet already provides with three different messaging systems and anonymously run indexes.

Are you aware of any YouTube-equivalent? Something that allows you to search user-generated/submitted content and content feeds and has a builtin player to display them.

I am aware that we are just one release away from serving video in a video-tag. That’s not as convenient as youtube (because it takes time to load), but much closer than before.

For convenience, we need m3u lists of video-chunks and a simple player shipped, since browsers cannot play m3u out of the box.

It is amazing that we're still not used to the idea that freedom has drawbacks, and that even with those drawbacks it's still preferable to the alternative.

Some of my best friends are witches ;)
