That's because Hasbro/WOTC/D&D is the big corporate punching bag.I agree no one should be the steward of the industry.
I do not agree that publishers will "slaughter" each other, there is enough to go around for everyone (assuming dnd burns to the ground, which it probably won't anytime soon). Tales of the Valiant and A5E both co-exist and don't "slaughter" each other for scraps at wotc's table. Both of them bring new variety and new ideas, and variety is the spice of life.
I'd hate to see the anti-WOTC clickbaiters if D&D's out the picture.
