Cloning discord is easy. Convincing everyone in a particular circle to move to a new solution is the challenge. You have to force a partition in the social network unless everyone in your group is happy to run both applications side by side (they won't be).
I was there when teamspeak was forced out by the demands of the group. There was no fighting it. My individual ideological preferences cannot defeat those of a collective. These people just want to play games. They don't want to take up arms in my weird nerd battle against COTS software, closed platforms or buggy applications.
