You can Google and pick your source, but the blunter article on NextWeb is T-Mobile One is garbage, and the EFF says it violates net neutrality while the more polite article is the BBC's T-Mobile deal 'may breach US net neutrality' rules. The BBC story explains clearly what T-Mobile announced: The NextWeb less polite story at the end opines: I think the fundamental problem here is that the carrier's argument is that folks like me who don't use much wireless data shouldn't have to pay as much as those who do. The problem with that argument is that while T-Mobile is hardly the biggest threat to a fair and equal internet, net neutrality can't have exceptions. IMHO technology is evolving too rapidly to not enforce net neutrality. As noted in the thread Google quietly tests wireless - fiber too expensive, to time consuming, wireless may be the future of universal internet access.
