If they're trying to get away from American infrastructure, the best argument would likely be that the Mastodon Inc (nonprofit) and Bluesky PBC are both registered in the United States. On the technical side, Nostr: * Has permanently referencable events and redundancy, meaning content can be archived and accessible beyond what AT/AP can do. * Is a lot more flexible as a protocol. AFAIK you can't do ebooks and geocaching on anything other than Nostr * Scaling a Nostr service is a lot easier and less resource intensive than scaling a large Activity Pub or AT based service * Doesn't rely on DNS (heavily American influenced) or a centralized servers for identity management Technical Drawbacks: * Key based identities would need to be abstracted for the average user. Good luck having them manage their own keys. Culture wise: * Nostr also lacks some of the extremists that have congregated on ActivityPub (both left and right) and AT (left). Sure the BTC people can get a bit loud sometimes, but it's nothing compared to the dark corners of the other two protocols. Finally, while it'd likely be considered a drawback to the German government, it'd be a benifit to the people that Nostr is decentralized enough that they can't rule it with an iron fist like they're likely eyeing with big centralized AT/AP services.
