I imagine this problem would be remedied by an acquisition.. or at least masked... Twitch (Amazon) seems a likely candidate, considering it's usage by Twitch users, and also the fact that Amazon doesn't really have skin in the game currently in the chat market (do they?), and could use a product like Discord in their ecosystem.
Some time ago, Twitch bought Curse, probably for the Curse App that already does voice and text chat. Also viewing streams and mod management for a handful of games.
