It seemed like the only thing he cared about was winning an Oscar and they didn't take that away from him and even allowed him to give a speech after winning, so yeah, he probably doesn't care about leaving the academy or being banned for 10 years. He got what he wanted. Bunch of idiots in Hollywood.
This is like trying to punish a kid for being bad and telling him no brussels sprouts for a week and instead he will have to eat ice cream for dinner every night.
