I have seen nothing but people ripshit that this isn't actual Teams, and so they can't log in to their work or school Teams tenants which they actually need to use. It's like the completely self-inflicted footgunning that they already committed a few years ago when they bought Skype and then immediately renamed their not-compatible enterprise chat system Skype for Business.
