I dunno man, we're in a Windows world. I word at an MSP and I am a linux enthusiast at heart, but I had to adapt to this Windows world and Teams is a huge part of that.
Do I wish that we could just use... idk an internal IRC server? Yeah sure, that'd be great.
But Teams allows us to organize meetings and communicate EFFECTIVELY.
Sometimes adaptation is a huge part of this industry, in my opinion. I think that if you dislike Teams, and can not adapt, you may not be effective in this job market unless you free-lance or find some small startup that ... doesn't use any of the modern communication applications.
Nowadays it's easy to setup your own conference server, and use webbased clients that don't require yet another Electron container. For instance, Galene(https://github.com/jech/galene) is an excellent resource-friendly SFU built on top of Pion(Golang).
Shameless plug: I'm the author of Pyrite(https://github.com/garage44/pyrite), an alternative WebRTC frontend for Galene
