@Kraut You're definitely correct that interpersonal drama, dramatic displays of gossip and "who's friends with who" comes with the territory. I appreciate your insight.
I think that, while a lot of people keep reinventing themselves, I see there are also people who lose all their fans after a series of fuckups. There's also people who get deplatformed and have to rebuild as opposed to enjoying the easy ride of uninterrupted success. (leafy compared to keemstar--who's making more money?) We don't always hear from them (thus don't think of them) for obvious reasons of losing their reach.
I've also seen examples YouTubers over the last 10 years whose bubbles burst and they REALLY fucked their lives up (debt, reputation permanently damaged, being a tard not capable of recovering) because they were banking on streamer income while it lasted. Some people get lucky and never had real skill.
These things may not ultimately kill shoe0nhead, she seems to have some skill at "being a brand" and it doesn't automatically kill a content creator to have their rep damaged. Drama can even
help if you do it right, people will support your cause (like itsagundam and pokimane). But it's a gamble, almost a Russian roulette. Playing with your reputation can kill you as an e-celeb if you fuck up in a cataclysmic way. Sometimes this means being capped at a permanent glass ceiling, never really growing past the point when you fucked up (ProJared).
Shoe0nhead has a fairly strong brand, and there are millions of people in the world for her to potentially draw on. I could see her fucking it up, though. Again, she might not "kill" her own brand by accident, but she could damage it greatly. She's obviously already sacrificed a lot of fans in favor of the leftoid audience, but as you say, if she has to jump ship on that... what next? There are so many other volatile factors in her life, her personal issues, mental illness. I can see her taking the wrong path and chimping out, instead of growing into a stable person who also does political commentary on the side.
The biggest risk I see for her is the fact that she lacks a real social life outside of the Internet. She doesn't have IRL friends by admission (steamer friends and troon goon) and her fiance dumped her, so whoever she gets with next will be a big deal. All the factors are there for them to spontaneously combust into a chimpout one day.
