What #Hasbro#WotC will decidedly NOT do is "kill" #DnD, not in any sense of the word. They will, eventually sell off the rights to the game, when it stops being profitable, because of their own stupidity.
But, "D&D", in the cultural sense, is a 50 year old industry-defining pasttime. It can't be "killed", even by malicious actors. Its spirit lives on eternally in too many of us for that to happen.
