Many internet providers with data caps (especially in mobile) will tell you that those limits exist to prevent network congestion -- that's not necessarily true, but it's the official line. However, Comcast isn't even trying to make that claim. Leaked support documents show that the cable giant's customer service reps will deny that the expanding internet caps are about congestion in any form. Instead, the ceilings are about "fairness" and offering a "more flexible policy" to subscribers. Also, Comcast is telling agents to avoid describing cap-free areas as having unlimited usage. Instead, staffers are supposed to tell you that unfettered areas are still subject to Comcast's longstanding 250GB soft cap -- the company just isn't "currently enforcing" the limit. In other words... it's unlimited.
