The pandemic is undoubtedly a huge crisis, but it's not as if the time before that wasn't also a different kind of crisis. Many people are now working from home and using videoconferencing, and the problems with the proprietary systems for that are starting to become well understood.
During the pandemic it may be even more important than before that your communications remain private. You don't need to use proprietary tools which spy on you or leak your data. This is where self-hosting or running p2p apps gains additional importance.
So does Freedombone have any better alternatives? The answer is yes.
The main apps which you can install for videoconferencing are NextCloud and Matrix/Riot. There is an app installable within NextCloud called NextCloud Talk, which then allows you to do video chat between multiple participants.
Riot (the web client for Matrix) can do video chat on a one-to-one basis, and you can do chat between three or more participants via the Jitsi integration. The particular Jitsi server which is used can be configured from the Freedombone Web admin system by selecting the Riot app and then choosing Settings. Unfortunately, Jitsi isn't an app within Freedombone because it's just not stable on low power hardware.
If you only need voice chat, not video, then Mumble is the best app to use. It has been around for a long time, works even with low bandwidth internet connections and is reasonably secure. This may be a more practical way to hang out with friends during lockdown.
Outside of the Freedombone project there is also other Free Software which you can try. Jami also does videoconferencing and so does qTox. qTox can also be routed through Tor for extra security. Jitsi Meet is also installable on Android or LineageOS via F-droid.
