Except even the stuff that could be replaced is just using it a Twitter alternative. Fountain could be a pure nostr app, host mp3s on relays, change the data structure and host the metadata on relays instead of RSS feeds, but it chooses to engage with the Twitter alternative and be a 'nostr' app.
Wavlake could do the same thing for music.
Even the apps that claim to be 'doing things different' are just using legacy protocols and tacking on the nostr Twitter feature.
Yep and any app that adds just one tiny Nostr feature is now a Nostr app. It all still seems like a money grab to me.
I think the phrase "give it time" is useful here.
Honestly, it'd be very hard for a team of developers to realize that what they slaved over to build for years and tune and tweek and bugfix was almost made unnecessary by a protocol someone built in tandem but they really didn't know about it's existence until they were deep in the hole.
But I will bet you that if we wait by the river long enough, the bodies of 'replaced by nostr protocol' code blocks will soon float by.
