It's really hard to tell without more detail! I tried doing a bit of digging, but he was a really early staffer to join Audioholics, and was editor-in-chief when he was fired. He's editor-in-chief of another site now, which it looks like he founded. You probably have to do something pretty bad to get publicly fired for cause when you were the editor-in-chief, and him having a new site he made himself isn't exactly an assurance of innocence either. Just... kinda a wild random footnote on a link on an article from over a decade ago.
I think the answer is that he set up another site called Audiogurus that was advertising itself as being "Audioholics store". This didn't go over well. Here's an article about that hints at it: https://www.audioholics.com/news/audioholics-e-store-name-ch...
From a bunch of digging it appears that, perhaps, Clint set up/joined some sites that were similar enough to his employers, without telling them, and when they found out they took that as him trying to siphon users off of their site, and fired him.
If this is true, whether that was wrong of Clint to do or not would depend on his contract.
