Seems like Comcast just takes issue with the term "cap" since from their perspective they don't "cap" at all, they just charge for overage.<p>The term data cap when there isn't a cap (i.e. you don't get cut off when exceeding) isn't really ideal. But it is the common term now.<p>It might just be better to call it Unlimited Vs. Pay As You Go data. Comcast's model is clearly what I'd call Pay As You Go or Pay Per Data.<p>But all of this argument over wording choice is unhelpful and won't really change the world no matter how it turns out. What does matter is choice, cost, and the ability to compare different ISP's relative data costs (i.e. no hidden cap/data fees).
