It's a really shitty situation. Skullgirls itself is actually the property of Autumn Games rather than Lab Zero itself so it may still be able to continue to get support when Lab Zero eventually falls to pieces.
But yeah, I was a fan of Mike and his work and it's very sad to hear that he's a total jackass.
I find this kind of statement really quite irritating.
Original Powerpuff, the show you actually like, still exists, the events of your childhood is actually completely untouched. You can go watch the show you like any time.
If you don't think you'll enjoy the new show, just don't watch it. It's literally that easy.
