Observing younger people in my family I think there has been a shift in recent years. When I was growing up being able to connect with friends outside of school, etc was a real privilege and something we had not had before services like MSN and MySpace.

These days kids are connected primary via online interactions from what I've seen. The young guys in my family spend hours chatting to friends on XBox while the girls play games like Roblox together and message on apps like TikTok / Snap. They don't need a Facebook because they're already connected through their other online activities. In fact when I've asked them about Facebook they don't even get why it's a thing and have told me flat out that it's a site for old people.

Even among people my age there is no long the desire to share things publicly and instead to connect via private messaging services which as OP suggested isn't going to be as easily monetisable.
