On the topic of non-US services:
Have you seen eurosky.tech, which is built on the AT protocol. Opinions? Experiences? Views?
Wouldn't it, today, still have a dependency to BlueSky? Or have I misunderstood how it (AT) works?
Apparently no one I know or am connected with is talking about it, as my search here in the Fediverse couldn't find a single post about it.
