If fb did meta as a separate company/project and not directly linked to zukerburg and maybe had fb as a partner company they would have made this whole thing feel less silly and less creepy.
Given that, then this seems to me that his passion for this is strong enough to overcome any reservations he or anyone around him might have. He's not dumb, and he surely knows what's what re current PR and image problems etc, so this looks (to me) like an expression of belief in what his vision is for the future.
They'd all be better served by turning it over to professionals, but they have to do it themselves.
The thing that puzzled me about the Meta presentation was that Zuckerburg could hire the best hair and makeup people in the world to at least help him look less creepy, but he doesn't. There's really no excuse for that. The look hurts his goals, but he sticks with it.
Mark hasn't seen them.
