I don't think you're missing anything. They literally just want JB to stand with KG and not apologise. They're angry at JB specifically, because conservatives attacked him over KG's comments, as JB is the bigger more well known figure and it makes a better headline.

I feel like it's an insane opinion if you have more than a passing of knowledge or compassion though, and I can't give you a definite reason why this commenter in particular is raging

Someone else gave a pretty good reason in a comment. It’s basically that the media is using JB’s name to drive engagement because everyone knows him and pretty much all the people who are now pissed at Jack black are just falling for rage bait. That’s kinda the type of explanation I was looking for. It’s capitalism. Capitalism is always the root of all problems. The media needs our attention and it’s using name recognition and faux drama to get it. End of story, pretty much.
