Not that they were in contact, they opposed disney (Taika watiti, edgar wright, etc.)
This was my takeaway, as well. Gunn handled this really well by sincerely apologizing and never badmouthing Disney publicly. Looks like that approach and ongoing meetings with Alan Horn eventually got him his job back.
Right now he's working on Jojo Rabbit which is in post-production, but he haven't been given another Marvel project yet. He definitely want to work with them again though.
This tweet is what made the whole ordeal so maddening. It's clearly an incredibly important project to him. I'm so glad he gets to make it.
I would bet money that Taika has something lined up at Marvel, likely Thor 4. But we won't find out the slate until after Endgame.
He made jokes about pedophilia around a decade ago. He apologized for it years ago and as recently as 2017 talked about how he feels like a much happier person now that he doesn't feel the need to make those edgy jokes. But he's also very vocal about his hatred of Trump. So people on the far-right dug through his tweets and found those old ones and Disney bowed to that and fired him.
