I think this is because they don’t have a server pushing the notifications.
You’re phone is directly talking to the Nostr protocol, there’s no third parties involved.

We’ll technically it is talking to the relays, but you get the idea.
There’s no central server like with everything else sending push notifications.
Oh right I should have realized that. Wonder if there is a serverless way to push the notification. Like how SimpleX does. I think only the notification goes to server but not the message or something like that
That’s above my pay grade 😅
