Late to the party but...OK. Think you had a post deleted yesterday for being a bit of a ****
I'll rephrase the question...
Please explain how Zoom is better or different from all the other video conferencing facilities out there? Why is it better than say Skype?
It's not necessarily better but...
It's very simple to use and does not require registration by the attendees. If you want to set up a quick meeting and invite people all they need is the link and a web browser. Audio is easy to adjust so it works reasonably well for remote music lessons also. It's free to use for 1:1 meetings and group meetings less that 40 mins.
Skype is a pain to set up,and you have to go through a registration process. Businesses tend to go for MS Teams but that can also be a pain when trying to find each other.
