Theres a reason why Google Fiber launched as they are calling out Internet companys to stop screwing over everyone.
Like for us here, We had adelphia, TWC bought them out, now we have TWC, Verizon Fios came in, but only to suburbs and refuses to come to the city, so we are also still screwed regarding TWC has majority of city because Verizon Fios wants to screw everyone over.
Regardless though, you should not be capped ....
We have a 5GB per day cap as well. If you're not torrenting massive amounts of data, then you really shouldn't hit it. I know that I've never come close to that much. The only time I might have come close is when I downloaded Adobe Master Collection to try it out (not torrented - this was legal). Then again, I download large things overnight, so maybe I didn't hit the cap. 3 GB day 1, 3GB day 2, if you know what I mean.
