I would say about Lay he have nothing to do with EXO now, and just taking their name, even this is bad he was dragging the whole EXO with him by supporting China statement over Korean war and his other things he have done supporting China genocide on minorities etc...is making Koreans mad and doing petition to not come to Korea...which really dragged the whole EXO down but SM probably doesn't care because his activities in China bring them money, and even I suspect if SM slowly wanted to get rid of EXO lol
