Konrad Hinsen I guess the answer is probably yes.
Also, I didnāt setup to build āsocial networkā. I mostly build initial version to publish things online with no social features(they were just requested later and in general social features are just an overlay layer).
about proprietary thing - the answer is yes.
But, to me it feels there is nice trade off in the sense that a lot of Apple Software is ālocal firstā
So all the messages in imessage, all the notes in apple notes, mails in apple mail and so on live on your laptop(and your Apple devices in general)
And this benefit is huge for me.
Eg all those modern decentralized or federated things like bluesky and mastodon are cool. But my data is never on my machine. The source of truth is always in some cloud database.
With my approach the source of truth are data on my devices.
Would I want that to be open format? Yes, ofc. That would be much better.
