So, I have been learning more about NOSTR, and I must say the idea is excellent. However, considering the world we live in and governments becoming more tyrannical worldwide, even the so-called "democratic" Western governments.

I work in cyber security and to play devis advocate over here and would like to ask  nostr:npub1sg6plzptd64u62a878hep2kev88swjh3tw00gjsfl8f237lmu63q0uf63m and  nostr:npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s what is to stop governments from blocking the NOSTR protocol on the ISP level?

I know it is encrypted and uses port 443 but can the traffic be identified and blocked?

In my opinion, governments don't like free speech where they can't control the narrative and I'm 100% sure that if NOSTR becomes the primary social media platform + any other use cases governments will try to shut It down.

 Thoughts?
