I came here to write exactly this about Louis. Hell, he was doing that long before he became a pariah.

I think that cries of "censorship!" from bien-pensant tech folks are largely overblown, and not only for the reasons cited in this thread. If some heterodox ideas of today truly will be part of future orthodoxies, they'll find a way - YouTube or not. A powerful concept that dies on the vine because it cannot get onto Facebook isn't a powerful concept.
