Except the entire use case for teams in our organization (and I’m sure many others) is basically just to chat and make calls. None of the extra stuff is useful to us.
Also you can look at slack which would also be a communications/collaboration platform, and weirdly enough the UX is fine and usable without training. Just admit MS shat the bed and made some Frankenstein abomination that no one knows how to use correctly. It’s pretty typical of Microsoft (and apple too) to just deflect that the user is doing it wrong instead of admitting they could improve the experience.
To add to your RV analogy, Microsoft is selling an RV to moms and dads that just want to drop their kids to school. Sure sometimes they go on vacation and the RV is nice, but it’s not what the user needs. It’s also exactly why users hate it, they are given a monster truck just to go to the shop. (Plus in the case of software, they could have it transform as needed. The communication part could look like a regular sedan, but instead you are forced into the RV format at all times)
Personally, I don’t give Microsoft the benefit of doubt. But technically I’m guessing they are not sending the audio data to their backend so no snooping there.
The rest of the meeting is free game however I’m pretty sure.
