Returning to the Game - Lemmy.world

I am recently coming back to D&D after an almost two decade hiatus. I have noticed that there seem to be a lot of sour grapes towards Hasbro and WotC. I know that there was the whole issue with the Open Game License, and that there has always been a portion of the community that think that the new edition has killed the game. But it seems a little extreme for these items (or at least my understanding). Is there another reason for the sour grapes or is there something that I am missing? It is hyped up for ratings/likes?
