I'm going to go ahead and surmise that other carriers are behind this attack. What else explains the FTC not going after AT&T and Verizon for equally bad and worse stuff? T-Mobile has explicitly halted this practice.
RB for Wii is a joke, no online, no DLC. You get it all and much more with GHWT. I don't understand Harmonix's decision to gimp the Wii version of RB. I guess they are big 360 supporters... seems to be a poor choice of platform when the Wii version of GH outsold everything else.
