Con No self-hosting avaliable
Discord is wholly hosted by Discord (the company), you cannot run private instances, and all servers are hosted on their infrastructure. For most people, this won't really impact their usage.
Con Proprietary software
Discord is closed-source, meaning their code isn't available for inspection or reproduction
Con Not a generic "team chat" tool
All the UI and the features are aimed specifically at communicating with your gaming team/clan.
Con Anti-privacy license terms
Con Disa doesen't follows the Google Design Guidelines
Hamburger Menu/Navigation Drawer (Side Menu):
Maybe a Launch screen?:
Con Smaller development team leading somewhat slow implementation of requested features
Though the main development (framework, etc) is moving along fine, things like quick reply and sending multiple images at once should've been in quicker.
Con Closed source
Disa is closed source, so the development speed is capped of their team, no external developer can help or add features that are not on the route of the team.
