He could have it but not post anything. I'd ask him about it.

Facebook messenger can be used independent of Facebook itself. You still have to have a Facebook account but using messenger doesn't mean you're using Facebook.

I would assume he must have the Facebook app.

Many people have it and don’t use it.
