Last year the Federal Trade Commission sued telecom giant AT&T over data throttling. According to Consumerist.com, 3.5 million AT&T customers were affected.

AT&T implemented a speed cap on users’ data, which, the FCC says, slowed it for as many as 12 days each month. AT&T disputes the FCC’s allegations.
