I used Adium, but same. For years, I had chat that was clean, simple, and it didn't matter what service people used. Then I worked for a company that used HipChat, which originally worked on Adium but stopped working at some point. Then the company switched to Slack. Then friends dumped AIM and GChat for Facebook Messenger and Signal and iMessage.

Now not only do I have a million chat apps again, but they're almost all a godawful resource hungry non-native UX disaster. :(
