I think the only response to this is for us all to remember that businesses are not our friends.
Spencer can talk the talk about wanting games to be everywhere for anyone to play them but his words are meaningless if Microsoft published titles are getting caught up in PC and Xbox exclusivity arrangements.
Sony can say what it wants about the dangers of Microsoft making games like CoD exclusive, but to this day they're doing work behind the scenes to keep major titles like FFXVI to themselves for as long as possible.
Business gonna business.
