Not at all, if his firing is incredibly public and harmful to his career, in the sense that it destroys it. Of course, the real prizes would be Hasbro CEO Chris Cocks and WotC president Cynthia Williams. Not just a firing like "okay, our visions didn't match and we need to amicably part ways" but scorched earth. If the thing the next guy hears is "yeah, the last time we tried to mess with D&D, the CEO, WotC president and person who came up with the plan all lost their jobs and are now working as sales assistants because no company will put them anywhere near an executive position" then that may be enough to make that executive think twice.
