Well, Irving Azoff is in a much different situation. He’s the most powerful person in the industry and whatever work he did with Axl/GNR is a footnote on his resume at best
These people aren’t exactly at the top of the game in the industry any longer. They got whatever power/notoriety they had from being alongside the band at its peak. Once that was over, they couldn’t use the experience to launch themselves upwards in any other substantial work in the industry. Once the band either didn’t trust them, they moved on to other people or the band didn’t have as much pull at the label after the mergers happened, their ride at that level was essentially over
