Yes, the Pope excommunicated him for basically opposing his papal stance on same-sex marriage, pro-immigration, and anti-capitalism but that stance is largely marketing, something we know because he's had to apologize TWICE after it leaked he used the Italian word for "faggot" in closed meetings.
So this is like when Mommy and Daddy fight and Mommy tells Daddy this marriage is over, but you don't really want to live with Mommy OR Daddy.
He wasn't kicked out because the Pope has a firm difference of opinion on the issues, he was kicked out for being vocal about it and doubting the Pope.
