At my previous job, I despised using Teams. I know, we're not supposed to be multitasking during meetings, but Teams harmed the performance of my computer so much during meetings that I was forced to focus on them. Heaven forbid if I had to be presenting (had to turn off incoming video for this to even be at all usable)! And, of course, one should assume if it's dragging performance down, that means the fans are going full speed the entire time. I have sensitive hearing, so I had to apply a power profile that turned down the fans without the computer overheating, which means lowering performance and making the Teams performance vampire worse.

And this wasn't on a mac. This is not a mac only issue.

I was so glad to learn my new job uses Slack, instead. It has its own set of problems, but it doesn't try to kill my computer.
