You are my brother! Good luck on your journey. I've made the same switch years ago and I can tell you it's only getting easier. A new employee told me about Slack, I researched it and yesterday I set up an alternative open source chat server on our own VPS (rocket.chat). It has ready built linux and android clients. Only a few years ago this would have never happened. Tomorrow it will be easier than today.
