FTC says: Okay for ISPs to block as long as they tell you they are doing it

To determine whether particular instances of throttling are deceptive, we would first evaluate what claims an ISP made to consumers about their services and how those claims are supported. We would look closely at any relevant research and evaluate the study’s design, scope, and results and consider how a study relates to a particular claim. To evaluate whether a practice was unfair, we would consider whether the alleged throttling had countervailing benefits and whether there were reasonable steps consumers could have taken to avoid it. We would also consider consumer injury, the number of consumers affected, and the need to prevent future misconduct.
