Overall that press release was a pretty positive, "hey things don't work out sometimes" big hugs all around/thanks for the memories. Except this part:
What's he getting at here?
He probably found out that he was making far less than lots of other endorsees, and tried to get more to bring his pay to that level...only to be told he wasn't famous enough. Sounds like PRS told him something like "we 20 grand like you, but we don't 50 grand like you. We 50 grand like artist XXX, who has a much bigger marketing placement than you" (just making up money numbers, I would have no clue what these deals actually are). Hiland's agent said something like "we get 50 or look elsewhere", and PRS said they couldn't do it.
