Activision deserves blame as well...I believe this is how it probably went down: Sony sees opportunity to sell more consoles by partnering with the creator of Halo. Sony offers Activision money to make Destiny exclusives for PS. Activision signs contract with Sony- not sure if it went out to competitive bid..but assuming it did, Microsoft dropped the ball there. Gaming community gets screwed, as these types of deals only benefit the corporations (obviously). What should've happened is that Activision should have given the middle finger to Sony and not taken extra money at the expense of gamers who want to play on xbox or pc. I also doubt Bungie gave much pushback to Activision making this deal considering the rumored bad blood with Microsoft...
