You make is sound like they are struggling. Some of those dudes are rich. I wouldn't worry about them. And they have enough fans they could stream other games and still be okay.
Maybe I'm an old man, but I really feel like the best thing for the streamers would be for them to get a real job. Streaming is a fragile source of income, and many streamers 'work' 16+ hours a day trying to make enough money to support themselves - with majority of them falling short.
Very few streamers make a good living from just playing games - many of the profitable channels grew through deceptive marketing dark patterns, allowing their audience to gamble, or being porn-lite.
Streaming does have some value, but it seems like there is disproportionately large amount of wasted productivity being put towards it in the last decade.
There’s no good solution.
