This is exactly what struck my eye. As someone from RU, I came to strongly identify "apolitical" with silent status quo supporters. Under an authoritarian regime, that means prosecuting people and lack of freedom of speech. Nostr? They'll just declare hosting a relay illegal and criminalize use, like they already did for other services.

They key is that your nostr app connects to hundreds of relays (and can work over Tor too), so that shutting down any single relay doesn't have notable effect.
