I'm not sure I share the view that Teams is terrible although I do occasionally have problems but I think it does share a lot of traits with modern software that I will call "spongeware" because it feels spongy.
Back in the day with pure desktop apps, you had crisp quick feedback when you clicked things, a window would open or be dismissed. It was hard to cause serious timing bugs because 1) Most things were written in code compiled to platform sdks and 2) Not much was network based 3) THe app worked more quickly than your clicking
What happens when you add not only network, but app frameworks that feel more like browsers than desktop apps, you click things and it takes a second to spring back, you think you clicked a button but nothing happens so you click it again, maybe the app is sending telemtry back to base or maybe it is needlessly loading a dataset from the network instead of just a local dll. What does it add up to? 1,000,000 unrepeatable bugs based on random timings and lockups, based on people doing things they didn't realise like double-clicking at the same time that anti-virus is scanning the network or your internet provider is having a blip!
There are still apps from the old-school like Notepad++ on Windows which feels solid and which auto-updates really easily instead of dynamically updating when you are trying to work but somehow they are not cool or don't tick the promise of "cross-platform development" which mostly means it's a bit crap on all platforms instead of great on one.
