So, I get you here and what you're saying. But companies at this scale argue they're "independently managed" or whatever.
With that context, for Facebook, there's really no way of saying that these 3 different brands are independent when it comes down to it.
It'd be much like Procter & Gamble saying their 100s of brands were all really different institutional entities.
