That's true, the concept of 'following' is about to change on Nostr. It's still a relic from the LSM days, and a lot of Nostr developers have a hard time letting it go. For me, it's already the case that I follow tons of people without formally following them, through the Tribes feature. And I 'follow' a bunch of people now not because their posts interest me, but because of what they sell on the NIP-99 marketplace (I'll decouple that eventually inshallah) and so their offers get sprinkled into my timeline.
