I don't know exact metrics, but most of the people who do thrive are MAGA/Q related. X22, Salty Cracker etc, but they use cross platform (Odysee, Rumble, Bitchute, Foxhole, their own site etc). The amount Salty Cracker rakes in per stream isn't trivial and he only streams 3 times a week. Those movements have their own bases on the .WIN sites, on GAB, Telegram, Truth Social etc.
It's 100% possible. You have to remember too, those people have long been kicked off YT, off Twitter, FB, Reddit etc. This isn't new to them. But it is likely "new" to Nick's audience. As the censorship gets broader, they'll start yeeting more normal creators and more people will just go over to other platforms.
