My best example is a friend who needed a video conference fast and needed an alternative to WebEx which stopped recognizing his video feed from one day to another (I couldn't find a solution for that too). Jitsi doesn't work for more then two. We tried to set up teams. Took too long (I tried it again a week later, people had issues with the invites, some got audio error messages even though it worked with zoom... we gave up). So I went for zoom. EVERYBODY (old people, first time video conferencing) was able to install it and it just worked flawlessly. Even I was surprised.

This is what people need these days and this is why Zoom is so popular.
