Skype was thriving on its own, then Microsoft bought it, and it died off slowly. I hope that's not the case for discord,(reply>), Everything Microsoft buys dies off slowly whereas they then push their own product which is very inferior.  Microsoft are idiots for not understanding this.  If Microsoft can't/doesn't buy a competitor they use actions that pushes them out of the market.  Netscape was superior over IE 20 years ago but Microsoft pushed them out.
