Almost nobody ever does that.
They complain about JewTube and announce they leave for a different platform, but never actually leave "because everyone is on JewTube".
Meanwhile, JewTubers won't leave because "all the content is on JewTube".

And I'm not surprised at all, alt tech all censor, if not now, they'll do later when they're "a REAL platform" (aka, as soon as investors start coming in).
Meanwhile, every alternative platform hosts all the content JewTube also hosts, because they use JewTube to mirror to everywhere else, meanwhile lots of JewTube content is not hosted elsewhere.
So if you have to be put up with less content, less people, you get little to no money on alt tech while you do on JewTube, and with censorship too on top of that, then what's the point of switching platforms?

So in a way I'm not surprised almost nobody wants to turn their words into action.
