https://medium.com/@chadwallacehart/atlassian-acquires-jitsi-what-it-means-f313621cfbcb analysis says acquisition all about Jitsi Video Bridge, which probably makes sense. JVB is a lot more successful in its space than the Jitsi clients (desktop and web) are in theirs. It may well make sense for Altassian to continue working on JVB but not on the clients.
