Discord was created to replace platforms like Skype, Teamspeak, and IRC, and all it did was become yet another Skype. It hogs resources, its management refuses to listen to complaints by its users, and its moderation is terrible. One wrong move and your Discord account of 6+ years is disabled because you said a number and they thought you were talking about your age.
I believe the scope of this suggestion should be extended to the concept of using alternative chat services like Matrix and not just IRC. While IRC is great, it's fairly outdated.
