TL;DR: Dana has been harboring some resentment over the way the Bucks were treated after Brawl Out. While The Elite themselves have decided to let bygones be bygones, she was never that happy with the situation.
Morffi, OTOH, simply had a better offer elsewhere.
Yikes, that’s a pretty awful snow globe.
I don’t think the merch problems entered into it, since AEW did apparently try to keep her on. But maybe this will be a net positive after all.
