I think they probably do since America is a fat nation and the Xbox One is American. So MS targeted fat people by having Mountain Dew and Doritos advertize it. The PS4 on the other hand is Japaneses and every one of them is skinny. So the PS4 might drive away the fat people since it doesn't have junk food advertizing it.

Except Sony went the Taco Bell route and fast food is definitely junk food, so you need a better argument in my opinion.
