>plays lol all the time it seems
Not really? It goes "today, 8 days ago, 9 days ago, 14 days ago, 16 days ago, 2 months ago". She seems to play it once in a blue moon, a few games a day. She plays normals too, not ranked. So she's far from the LoL addict you people seem to pain her as. I know she streams pretty damn rarely, but everything else sounds like pure rrats. I don't watch her myself, but assuming that she hates Hololive or anything is silly. And I checked her channel, she was streaming maybe once a week even two years ago.
Here's my rrat: when she joined Hololive, she did so because it was a small group doing vtubing mostly for the love of the craft (Hololive would truly explode only a year after she joined), and she never planned to be a hardcore streamer, doing it every other day for fun and hanging out with other girls. She didn't sign up for a part in a world-famous idol agency that will redefine online entertainment. And she doesn't want to force herself into this role, probably because she doesn't feel like she fits it, or because she has a stable living IRL and doesn't want to throw everything out for streaming (which is damn smart, if you ask me).
Here's a protip - never assume malicious intent in situations which can be explained by a simple lack of foresight.
