mpicpp (3454017) writes with this excerpt from Ars Technica about Comcast's data caps that aren't data caps:Customers must pay more if they exceed limits — but it's not a cap, Comcast says. For the past couple of years, Comcast has been trying to convince journalists and the general public that it doesn't impose any "data caps" on its Internet service. ... That's despite the fact that Comcast in some cities enforces limits on the amount of data customers can use and issues financial penalties for using more than the allotment. Comcast has said this type of billing will probably roll out to its entire national footprint within five years, perhaps alongside a pricier option to buy unlimited data. ... Comcast's then-new approach was touted to "effectively offer unlimited usage of our services because customers will have the ability to buy as much data as they want."
