The fundamental difference here is that Robbers does not (yet) have rubber-stamped approval to screw customers of its reseller services for overages.
Blue and Red have been screwing their own customers on overages for some time. Blue recently paid off the right people to get approval to screw GAS "resellers" offering DSL service on its network e.g. Teksavvy.
Red is now requesting the same right to screw TPIA "resellers" offering cable service on its network e.g. Teksavvy.
Blue and Red have two objectives in mind;
1. Clamp down on bandwidth, thus making it very expensive to use the internet for streaming high-data-rate content (video), thus protecting their own TV distribution businesses.
2. Spike the competition. Stem the tide of defections to "reseller" services offering lower prices and unlimited bandwidth on the blue and red networks.
IMHO, Blue and Red would like nothing more than to revert us back to dial-up internet, since that would effectively kill video availability on that medium.
