Microsoft Teams already is already terrible UX, we have nowhere to go but up. Perhaps you are unaware, and if so, you should be thankful you don’t have to lose time using it. There are objectively better solutions available.

I too hate Microsoft teams but it can always get worse, you have no idea.

I'm in several Slack teams for non profits and professional orgs, Teams for a client or two, IRC and Matrix servers for digital archiving ops, Signal/WhatsApp/GroupMe/Telegram groups, etc. I have been in tech for 25+ years, I am familiar with the extremes. You are right, things can be bad, that is the point of systems engineering: to drive directionally towards continual improvement. Success is never assured, but throwing our hands up and giving up is not reasonable. Make a plan, work the plan. Default to action. Work is hard.

I recommend "Thinking in Systems" by Donella H. Meadows (ISBN13 9781603580557) on this topic [1]. It's ~$10 on Amazon as of this comment, and the PDF is easy to find with a quick web search.

Care to give me an example to satisfy my morbid curiosity? I have used a lot of really bad chat clients over the year and Microsft's rewritten Skype is one of only a handful worse than Teams. Teams is not the worst but it is on my top 3 or 5 worst of the 30+ chat clients I have used. I have heard Lynk also was really bad but I never used it. Microsoft certainly has some of the worst.

Element is bad but it is way better than Teams from my experience.

Matrix is so much worse than Team it will make your head spin. It suffers from design by committee to an unbelievable extent, and its various end-to-end security features are wonderful from a privacy standpoint but make things much much more complicated.

Having used both I think you are way too kind on Teams.

I've used both and written code to integrate into both. You never have to worry about, for example, losing access to all previous messages in your Teams channels if you get a new phone.
