TBH, I still have problems with Nostr decentralisation. I don’t think that we’re able to set up relevant relays as fast as they are going to tear them down (should they want it to).
But hey, prove me wrong.

There's a lot of relays for the "them" to tear down. Say they come close, the blastr's can be turned on.
They can't take down tor only relays. No doubt they've been aiming to take down Dread on tor for years.
Nostr's not under such an attack but the second there's a hint of fear, relays go tor only and onion urls are spread around.
Media links are the main point of failure we still have. Not sure why there's little attention in this regard.
