The DMsGuild isn't hurting for material, from what I can see, and WotC is recruiting from the authors there. There may be people who do not want to accept WotC's terms, but there were people who didn't want to submit to TSR for their magazine, either.If it's structured in a way to make the people of that "same pool of talent" avoid it then it does not pull from "that same pool of talent" or remain the same in any essence.
