Discord missed an opportunity to become the video calling and chat king, the smoothness of joining and leaving a group video chat when you please and the high quality video, audio and app support was exactly the kind of "just like being in the office but virtual" experience that teams, skype, slack, zoom, meet, etc lack. During peak covid it was a godsend having calls with friends and playing games together.

My dream service would be very like discord but with scheduled meeting support and completely open source and self hostable.

I suspect quite a few people still use Zoom out of habit / procedure, but you can see on its stock market value that it really was a pandemic success, its stock market dropped and flattened out after 2022.

Zoom is widely used in US city and state government departments because of the ease of use and pricing, basically free.

My company uses Teams and Zoom. Every Teams meeting is a disaster compared to Zoom. At least it's not Amazon Chime. IDK how AWS Support survives that

A deaf colleague massively preferred Zoom to Teams because the video quality on Zoom allowed a lot more sign language nuance to transfer.

I have literally never once used teams officially in any degree. Every call i made before i graduated high school was skype, every school and graduate and job call I've ever made has been zoom.

It's entirely Zoom for my branch of academia.
