No, it’s not an issue, but it might be soon. Median usage is 200GB a month of streaming data (the Comcast limit is one terabyte a month, and then users have to pay). Sure, “200GB a month is still a good distance away from that 1TB limit, but it’s a considerable jump from just 60GB a month just a couple of years ago, and that likely means that even more customers are meeting or exceeding that data cap, although Comcast didn’t reveal that figure.” – The Verge
