This quote was from me, not Steel Inquisitor.
And yes, Heard is covered. But in this case, we have yet to get anything substantial for those people in power doing anything really abusive despite Fisher's claims and it just increasingly seems like he's bitter his role was reduced. Them upending the Snyder cut and making a bad patch job to release in theaters sucks, but doesn't seem to warrant a loaded label like "abuse." And it's also coming out after the theatrical cut bombed and we're getting an unprecedented Snyder Cut for HBO anyway, so if there was indeed nothing more than Joss being an asshole in a rushed, tense studio driven situation that trimmed the original planned movie, it seems petty. Unless we for sure get something more solid from this.
And yes, like Steel Inquisitor said, Affleck especially isn't an extra or up and coming actor low on the totem pole here. This ongoing feud is making the producers and Whedon out to be villains, and maybe they are, but so far it just seems they clashed with Snyder's vision. Meanwhile, some of the actors behind it have done some problematic things that warrant side eying, but we're not talking about it because they don't shape the environment of the set?
