I mean, who's really surprised? She supported Charisma Carpenter IIRC and while for years I pretty much didn't pay any attention to him (mostly because I don't read anything to stars, directors, etc. aside when friends talk about it, which mean nearly never ever), it was very obvious to me that this guy seemed to have a very toxic way of dealing with women.
The fact that she finally comes out about it, only more than a decade after, speaks about the power that man has/still had over Hollywood during that time though.
