He was working freelance at the time, and working for various RPG companies. Little known, but WotC was actually one of them from what I've heard, though he had far more work via other places.
WotC also defined what they were looking for, and Ebberon basically does not fill out what they defined as one of the criteria...which makes on go...hmmm....
It was great for him to get it (as he was freelance, not an employee, and struggling at that), but that was totally not a legit...even handed...fair way to do it.
Hot take, maybe. There's a reason most contests disqualify (or have it in their rules, a few companies still break those rules at times, the difference is that they then are eventually sued in court by unhappy norms who truly are disconnected from that company when inspired by lawyers for an easy money take...for the lawyers) employees (which also normally includes freelancers if they are in that same industry), family members, and certain friends of employees or family.
