IG, TikTok, Youtube and others are corporation's property. Nostr is not social media, it is open protocol, it doen't need business model. It will live if it needed, it will die if it not.

That is the explanation I needed!
Can it survive without business models that work?
I guess that’s the question I was trying to get to!
Open source projects are not necessarily intended to be potentially profitable. When a protocol or other software product is in demand, then developers make money by adapting such a protocol for the most popular type of use. For example, Bitcoin. Or Linux. Or XMPP/Jabber. Or Apache, nginx (not quite open source, but still). And many, many others. I think Nostr will be fine.
