Do you think graduated/terminated corporate vtubers hang on to their models even though they can't use them anymore? Like I'm sure they're probably told to get rid of them but if I were them I'd back up that shit on a USB or something, especially if it's a really good model. Then imagine years from now the company dies because setting aside the companies that are already dying, there is no way that vtuber corporations as a whole will last forever. Then when there's nobody that can sue you, you pull out the old model and go "Surprise! I'm back."
