I think being a member of the Academy just gives you a vote in the Oscars. All you need to be in movies is a SAG card. However, he might have trouble getting some jobs in the future over this, which isn't unreasonable.
There's also history. Chris Rock made fun of her at the 2016 Oscars. Said, "Jada boycotting the Oscars is like me boycotting Rihanna's panties...I wasn't invited."
To quote Chris, I'm not saying it wasn't wrong...but I understand.
