No, that IS how they are treating him. Read the damn books. He can't even control his own teams, he's antagonizing literally EVERYONE, even the people who are supposed to work for him. He's trying to herd giraffes and it's obviously not working out, he's essentially kept afloat by momentum alone.
People aren't doing anything about him mainly because they're still trying to get their bearings. (His villains are trying to plot the way to get rid of him to their best advantage, and the heroes are trying to figure out something similar when they aren't just running for the moment)
