Sadly, unless your indie career is better, people will almost always take any corpo opportunity because you're guaranteed at least some kind of boost. For example Shoto would never have to join a corpo or Vshitstain, but assfuck mcgee with 7 viewers for the last 4 years would likely try his hand and even if he hits 100 ccv after joining, he still has merch (better than no merch) and still guaranteed some kind of return versus being a 7 view nobody getting nothing. I think their biggest mistake is thinking they can pump and dump niji like some previous ex-livers did and gained more support (and money) after leaving.
It would be a pretty hilarious cycle.
