I think the good news is that the foundation is right. Nostr is so modular and based on simple cryptographic primitives with such little consensus that the most decentralized and free version should always exist.
At this point it seems inevitable that true decentralization and freedom comes at a cost that most folks won’t accept. My biggest hope is that we can at least make the decentralized and free options popular enough that the bigger, convenient platforms are effectively forced to be interoperable. The fun part is figuring out what levers we have to do that… maximizing numbers is a big part, but not the whole story - if the content is better or more diverse then other networks will be forced to adopt.
