Jon Brodkin has to write a "ISPs are evil, support net neutrality" article literally daily, but data caps are very simple: A way for Comcast to increase the cost of service to heavier service users, rather than raising prices for all customers equally.
A 1TB cap feels reasonable.
If anything, Comcast's past behaviors warrants not giving them the benefit of doubt.
edit: I guess a downvote indicates that I'm wrong. The lowering of price is definitely due to the overwhelming generosity of Comcast. /s
Data caps only exist in the context of an ISP covering their ass for overselling. "Fair" and "reasonable" are just a matter of perspective, one I can never sign onto when they're the fine print on misleadingly marketed product.
