Kind of, especially with PPP and Godwinson, the problem isn't making money in of itself but that this almost inevitably leads to a drop in content quality, parasocial relationships (woooaaaah signal boot with one THOUSAND dollars there guys) and scummy behaviour.
Without the grift, PPP wouldnt fire up a stream unless there is something worth talking about. Contrast that to today, where they will pause on Nick Fuentes talking about something mundane and go on and on about how the way he is breathing the air is totally evidence he's gay. So they just spaff out content to make a quick buck.
With that said - it's not that people can't do this without going scummy, or that noone should do it. Rekeita has managed to monetize and still putting out content that is engaging - and probably better - and Jewsh doesn't seem to have changed his streaming at all.
Yet the majority of people who try it inevitably end up like PPP and Warski.
