Rolfe is something of youtube aristocracy, having been on youtube since about 2006, so seeing him mirror content off of youtube is, in my opinion, a promising sign that we're breaking through the noise, even if he did it for purely pragmatic reasons. Rolfe is a fairly apolitical guy, so don't expect a lot of "Row Row, Fight the Powah" from him, but it proves that even bigger independent names( 3.55M subs and 1,978,090,622 views on youtube) are feeling the stifling of bigtech censorship and shopping around for alternatives.
Do what you want, but it might be a good idea if fans of his content show him that we'll follow him wherever he finds a home, even if youtube decides to abuse him.
Good question.
I know, because I found it through embedded videos on his personal website, cinemassacre.com , which I know is his, because he mentions it in quite a few of his videos.
