The reason we don't have more competition/carriers is the barrier to entry cost. When the barrier to entry is too great, government must regulate to prevent monopolistic policies from ruling the day. Think utility companies, auto manufacturers, airline industry, oil companies, etc. Too much government regulation is NOT what prevents you or I from starting a nationwide cellular company. Infrastructure, massive geographic barriers and start up costs prevent entry. Therefore, the government needs to tell these monopolistic vultures to play fair with the consumers. This FaceTime policy is so heinous it wreaks of criminality!!!
AT&T does not offer FaceTime over WiFi, Apple does. It is through Apple's servers that this works, not AT&T! Again, if I'm paying for 5GB on a private line...why do I need to share this data with a family for the FaceTime feature to work over cellular? I found it funny AT&T mentioned they offer this over WiFi to their customers already (as if Android users can do this over WiFi as well).
