What I do want to understand is, why would anyone use this instead of NextCloud, for example.
I'm all for having local setups though, as a general policy.
It's just that from what I know, the difference in feature sets is just too huge right now.
Was a pretty good idea but there wasn’t any sustainable business model/funding and it was also pre docker era which would have made things more secure/containerised and easier to maintain.
(Personally I also find Nextcloud incredibly sluggish, but it is quite popular so it must work better for others.)
