Interesting. Possibly useful to some. I have also discovered that the simplest, most privacy-friendly way to update location is just to do it manually when you change location.
I have a simple script that does this by querying OpenStreetMap’s Nominatim server with the city name. It feeds the resulting coordinates thru a Python library that deduces the timezone, and sets the system time to this.
Interesting read, somewhat enlightening.
But IMO, from the point of view of interoperability, it was bad enough having competing corporate social networks. We don’t want to replace that with competing open meta-networks. And yet ActivityPub and ATProto seem to use completely different paradigms, which would make bridging them pretty hard. Frustrating.
