About a month ago I evaluated it again, hoping it would have changed since I last evaluated it 2-3 years ago. But it still had terrible quality issues. I want to use SIP instead of Skype, and I want to tell other people to use SIP, but for that to happen Jitsi needs to stop sucking :(
I can only hope this acquisition means Jitsi gets better to a point where I can recommend it, and use it myself. There's a lot to hate about Skype. It's a closed protocol, it's owned by MS, and it's UI is garbage. But everytime I use it I don't suffer from any A/V quality issues, which is actually the point.
 By this I mean scratchy audio and video between two test laptops. Whereas Skype had no such problems.
We have been focusing our efforts on Jitsi Meet for past few years: https://jitsi.org/jitsi-meet/
Is it feasible that the old Jitsi gets a rebirth? It'd be popular, I'm sure.
I feel sorry for anyone that has been stuck with Skype anytime after 2007.

I guess my question is that is it really something people don't care for? In my experience it's just vital and teams that don't do it appear worse off for it. Admitting my bias here though. ;)
I'm part of the Jitsi team, and made the transition from Atlassian to 8x8. I'm happy to answer questions if any, to the best of my ability / capacity.
I'm curious why that's happening, was there some sort of leadership change that's trying to focus on "core business"?
That said, they pushed out an update about 3-4 months ago that improved stability a lot.
