My guess is that, at least initially, the EU will look at individual companies in the Nostr space, either apps or relays, and make some demands of the bigger ones.

We can keep an eye on large Mastodon instances to see what happens there. I don't think the EU treats ActivityPub as a single entity either.

For now however, we are small. Or at least appear that way. nostr:note1r426xecmv6a0n57ygqk8strm46fw543uv5a3w0a5tuusq7ssytkscgqh7z
