I would argue that the thing that makes the "Meta" ecosystem actually appealing to most people isn't the actual services, it's the single universal sign-on. With one login, I can use Messenger, all the FB services, Occulus, and a ton of games that use FB accts for backup.
That's the simplicity people are actually looking for, the services are secondary and rise/fall constantly (RIP FB's Games and Video) as the needs, wants, and interests of the community rise and fall.
