Folks are like that. They like saying "my shit is better than your shit, now deal with it"
MS have done cut these type of deals in the past when they were market leader. But this goes to show that this is a business and companies will do what's in the best interests of their bottom lines. Sony may want this to come across as good for the gamers, but make no mistake they're doing it for themselves.
Seriously, what does someone who owns only a PS4 get out of Destiny content bring exclusive to their platform for a year besides bragging and putting down other folks and lording the fact that they have it for a year? Nothing. Absolutely nothing.
Xbox or PC folks getting the same content day and date wouldn't mar the experience or make it any less fun. Moreover I think this sucks for developers. I can't speak for them, but if I was a dev I'd want my content to be enjoyed by as many folks as possible.
Many will think Phil is coming across as a hypocrite and maybe he is when his company has cut these type of deals in the past, but I'm glad he is speaking against this and hopefully these type of practices come to an end. It isn't fair for either player base on PS4/Xbox or PC.
