I mean... plenty of youtubers and channels are doing exactly that. Ian McCollum (Forgotten Weapons) and the "educational" gun youtubers have History of Weapons and War. A bunch of creators did Nebula. Corridor Digital have their channel. That comedy channel that came from college humor have their own site? Same with those two channels that pissed everyone off in the past few weeks? And Linus Media Group have been trying to add "we run a shitty version of youtube" to their grift for years now. And Rooster Teeth and Giant Bomb had their own video site for basically the entirety of their runs.

Let alone stuff like Utreon and the other one. And then there are the various successors to liveleak that are basically about spamming yu with an insane amount of spyware and ads in exchange for letting you upload faces of death.

And while I think it is a fundamentally flawed idea that mostly just does the legwork for those sites to run the software: Peertube is a thing and there are plenty of instances that exist.

So I am REALLY curious what evil organization you think is waiting to kill anything that is not made by Youtube. If you comply with DMCA requests and don't host CSAM then it is just a function of whether you can afford it.

Which... is the real issue. There is just a ridiculous volume of storage and bandwidth required for even a "small" youtube. Which is why almost all of the successful "alternatives" only really host a very small subset of videos.
