Twitter's revenue is pretty small compared to Meta's. In order for Meta to actually value the revenue generated they'll want active users to reach what Twitter had at it's peak. That's not going to be this year. And the app will have to be fantastic from a user experience point of view for awhile to grow enough to get there.

So yea, duh, Meta will monetize it. But it'll be an app hellbent on growing while being subsidized by Meta until then.
