Blizzard is owned by Activision. I see plenty of communication between the "blues" on blizzard and their community. They actually acknowledge their feedback forums, and they explain any and all patchnotes with full detail on why they are making changes. They also put out tons more content at a faster pace, for free, than Bungie so far. Activision is probably only responsible for the exclusive content, Bungie has probably asked them to keep content from xbox users longer due to the fact Bungie and Microsoft are "sour" towards each other. But hey...what's a few pissed off xbox players over getting even with MS?
