So Onces, me included, have ranted for months about JYPE not giving members opportunities for growth including solo and subunit releases, variety show and TV/movie roles, CF gigs, etc. But maybe the plain truth of the matter is that the members themselves are happy and content with the status quo. Mina basically spilled the tea about herself in her recent Lego video where she talked about how she rarely leaves her apartment, the only time she goes out is to do her Twice schedule. It's pretty clear that she's happy just staying home and playing games and doing her hobbies.
As for Blackpink, so many Blinks have complained about the lack of comebacks and the basic choreo. But maybe the plain truth of the matter is that the members themselves are happy with the status quo. Jennie basically admitted how hard it is on her body to practice for hours every day in their Netflix special. Plus most of them have been training hardcore for a decade at least. Maybe the members are ok with lots of downtime between comebacks and not having to do crazy difficult Itzy-level choreo for every comeback.
So in conclusion, maybe Kpop stans need to stop scapegoating companies for what they perceive as "mistreatment", and should just accept that their faves could be ok with their current situations. After all, neither Mina nor Jennie, nor any member of Twice or BP, are living on the streets begging for quarters. They are all banking enough money to be able to retire and never have to work again.
