Source? I see the repo as MIT licensed so I don’t see why forking it and hosting our own instance would be a problem.

Its FOSS (or I guess FLOSS for this case since they are French lol), meaning it doesn’t matter if the people creating the app are “good” or “bad” actors. A “good” actor can always create a fork or host their own instance.

I recommend GNOME because it has a very good philosophy on Free/Libre software and it doesn’t stray far from it.
