Probably because some Xbox only fans have never been able to except that Sony has had greater success in the console buisnes or even better performing hardware at times, to varying degrees of course. It stems right back to the original Xbox days. Some just hate PlayStation even if they won't specifically say that and they get bent out of shape because they can't understand why their choice isn't the leader or the most successful. That's why you see all this 14 tf and secret sauce nonsense, happens all the time. Life would be simpler if they just bought both like most of us will problem solved.
