Demons and Devils being any alignment is fucktarded. I have no issue with an extremely rare exception straying from the usual routine of torture sodomy and forcing the damned to eat feces and such, but that means neutral in a 1 in a 100 million case, not anyone just be any alignment. I agree many cultures have the idea of troublesome spirits being demons, but that is not the point of view of western culture influenced by Christianity....which is what the creator of the game and the culture it is marketed to have as a vision of what a demon/devil is...evil incarnate.
I am not bothered by such a dumb thing though, I do not buy or play dungeons and dragons. I do not think wizards is headed for broke either, not for a very, very long time. They have big, big money sunk into them and that sort of money can live with a dip in profits for a while for the sake of social engineering if needed. I do think they will lose fans/players over time, but they are a massive operation that knows how to market and they will find players. Their biggest issue is going to be when you hire based on idiot criteria (race/sexuality/etc) instead of talent and creativity you eventually get shit for product across the board. That time will come given their direction but it will not be for a while as momentum will carry them a very long ways first. There is also a point where the bean counters talk to the higher ups and social engineering gets dumped to make money, so there might be a course correction in their direction as well.
All that said, if they do better, worse, cease to exist, become something everyone plays it does not matter to me, I am done with em.
