yeah it makes no sense whatsoever.
Why the hell would someone complain about an entirely optional experience? That would be like bitching at Fallout and Elder Scrolls for allowing 3rd person view as an option. Or about Killzone, Resistance 3, and Littlebigplanet 2 having Move support. Or for PS3 haveing 3D support.
In other words bitching about something which is ENTIRELY optional is plain rediculous.
