If you understand and like freedom money, then it's not hard to understand freedom communication. If they don't, then it most likely means that they're into bitcoin for different reasons than they think and/or they feel validated by their followers and interactions with them. I get the last part. After all, humans are social creatures. However, all it takes is a little bit of proof of work, which they claim to understand, to be social on Nostr and enjoy being here.
