The thing is, the exclusive content hurts PS players as well. Both sides end up with a worse product. We'll never get the exclusive strike in the nightfall rotation or have the exclusive weapon made available through Xur as well, since the choices are all synced between the platforms and the other two platforms don't have access to that content.
I wish the entire PS userbase would speak out against the practice of getting us exclusive content. It does no one good. Well, I guess it gets Sony the occasional consumer that doesn't yet own a next gen console and is deciding which one they want based entirely on Destiny, but I don't imagine that's a particularly large number of customers.
