I have been using Microsoft Teams and its hard to imagine anyone buying it for the user experience, yet it's not an unpopular choice. It seems more likely to me that the fact that the organization already had a bunch of managed Microsoft software was the most important selling point, and that this is a common situation. "Admin experience" if you will. So sure, Teams gets some things right, UX-wise, but for every "notify the user if they're speaking while they are muted" there's a "randomly scroll the chat back down while you're looking through history", a "randomly make it impossible to erase a link with backspace in the chat box" or a "don't let people see who is participating in the conference", and there's little incentive for them to avoid crap like it and avoiding whole categories of bugs because people are buying it for other reasons.
