That may be the intention, but it wont stop them being called hypocrites for talking about doing more for climate change meanwhile thier company (through them) are selling 4 versions of the same album to generate more sales, knowing full well fans will try to collect all the photocards and end up buying hundreds more albums that they need which all goes into landfill.
But unlike western celebrities who often only have to be held to account for thier own actions, the girls will be held to account for an industry wide problem, and they will be the face for it.
It may get attention, but it's not going to make any difference sadly.
I don't really think anybody cares what 20 haters on Twitter are going to say.
