Yes, from here on out all request for Teams meetings are going to be answered:
"Thanks for your invitation. The discussion you proposed is important to me, so let me propose that we do not use Teams.
Teams has not performed reliably. I cannot guarantee that my audio link will work and hence we strongly discourage the use of Teams for communication. We have found Zoom, Google Meeting, Skype, and Webex to work just fine. Please let us know if you wish to reschedule with one of those systems, or if you'd like me to schedule the meeting with google meeting."
Feel free to use this.
Everyone else seems to have figured out how to have their system work with Ubuntu, but if MS doesn't care to put the work in, I have no inclination to waste my or my company's time on their products.
