Right, I worked on a async non-blocking project in C++ in the 90s. It was a lot simpler than any modern project, no cloud, no yaml, no containers, no fancy security. Sure it didn't have a pretty web interface but was great software.
You could've cited Slack or Discord. Teams is an anomaly in horrible software quality that *only* Microsoft can manage to produce (also see OneNote (but DON'T see VS Code -- that's somehow really efficient despite being Electron!)).
