The fact that more and more apps built on Nostr is treating it like a public key based remotestorage.io is a good sign.
If DWNs didn't really suck at shipping, they might have became the standard for per-user backends already, but here we are.
Nostr was designed to be a Twitter alternative and made a lot of sacrifices to reach that, and the nsecbunker (giving your key to a server) is a clear sign of that, it devolves publickeys into a server owned identity.
Let's try again with more focus on local-first apps and proper key management.
