(jetsetpress)In June, the FCC proposed a potentially $100 million fine against AT&T for allegedly failing to disclose to its “unlimited” data plan subscribers the extent to which their data access could be throttled if they used too much of it in any given month. The company recently responded to the allegations, and let’s just say that AT&T isn’t exactly thrilled. According to AT&T’s official response [PDF], the FCC’s proposal “flouts the most basic principles of fairness, due process, and responsible enforcement.” The Commission accused AT&T of violating the so-called Transparency Rule, which requires broadband providers to publicly disclose sufficient and accurate information about their network management practices, performance, and commercial terms of their services. The FCC’s problem wasn’t necessarily that AT&T was throttling data speeds of certain unlimited users who gobbled up the most data each month.
