since Discord is very popular in the gaming world, one can only wonder what the future would bring seeing how another acquisition of Microsoft in this space ended, namely Mixer (Twitch-like service).
Skype was the previous home of many of the communities that were the early adopters of discord, and they left after years of MS running the show, which seems like a better comparison to me
While Discord is like the Twitch of its market: The most popular choice and with their specific feature set they don't even have any real competition.
