This has critical flaws.
The video starts off about groupthink existing as the negative force against free speech..
Yet at 24:20 Matt goes on to say:

If there's one small faction of the community that is doing something that the rest of the community doesn't like, I'm sure you'll find the rest of the community turning on those people.

So groupthink?

He also makes point about obeying local laws and that there will always be an ability to mute data if higher powers deem it necessary. So how will it be any different from mainstream?
