From experience i've been banned from my relay list by IP address and forced now to use dummy accounts like this one on mobile because i know they want me to copy my private key and paste into a likely compromised/paid off dev's app. So yes, gov can ban/silence/limit individuals and so by extension shadow ban (make useless to freedom) #nostr.
I see. If you ever have the time, ability and capacity, feel free to make a video, blog or something else about. I would love to inshallah see it. The point is, I really appreciate #nostr. However, I do not think that it is that kind of freedom as many want to believe. Freedom is something that cannot be taken away from governments - or at least I would define freedom as such.
