They are not ridiculous at all. Time Warner is trying to shut out competition by putting caps in place and charging for exceeding those caps. They are trying to compete with Netflix, Apple Movie, etc and by charging for bandwidth, they make those other services unattractive because of the cost involved. Since TW owns the lines, they can push out their own content and no one pays, but pulling in content over the web, they cannot control except by charging for it.
We (as humans) have the technological capability to bring high-speed Internet to practically everywhere on the planet. Here in the US we do not do that because the good of the people comes secondary to the good of the corporations. Always has, always will because money is involved and here the corporations run the country. Sad yes, but unfortunately true.
