I mean think about the huge financial loss this off-collab would have been. Not being able to stream for like a week in exchange for a shitty one-time meme stream? Nah. She knows cumsharts don't give a shit about hololive and only care about her, so they wouldn't even know this was happening (and if they did they still wouldn't watch because Gura is being "drowned out" or whatever).
Remember money is the only reason Gura is in this game (as evidenced by selling out to Taco Bell like generic shilltuber #28237).
