very good - the real problem is not 'in jitsi'
What do you like best about the product?
It's free, open source, as easy to use as anything else out there, if not easier. It's no encumbered by being associated with the big companies, and does not obsessively try to sell you all the nonsense that Zoom seems to be pushing on you
What do you dislike about the product?
The problem is that it is not well known enough - if others are not willing to trust it (because they do not know the name) or if they are not willing to try it (because learning another tool is just so difficult) then it is just very, very difficult to get adoption of it for use with everyone you might need to use it with.
What problems is the product solving and how is that benefiting you?
It allows me to escape Zoom, and is so much simpler without the millions of settings that has, without the pushy attempts to get you to buy things, and without trying to over integrate things with your email and everything else. It is so much easier than Teams to use, and when people try it, then they generally are fine with it - it does not cost either if you self-host it. Open source is a benefit when it comes to security.
