They do seem to be rather twisting words to appear not to be imposing limits.
However, my question is: why are data caps such a bad thing? Most slashdotters seem to think that ISPs can provide truly unlimited bandwidth for zero cost, and given that most slashdotters are pretty technical I don't see how they can consider this to be a rational view. If large numbers of customers try to use large amounts of bandwidth at the same time, the only way an ISP can maintain a reasonable service is by upgrading their infrastructure. Sure, there's a lot of dark fibre already laid, but the hardware to put it into use is not free, nor is the engineer time required to install and maintain that hardware, nor is the power that the hardware draws.
So, whilst I acknowledge that a lot of slashdotters seem to think it is their god given right to max out their internet connection torrenting "moviez" 24/7, I have to question why the majority of internet users (who don't do this) should be expected to subsidise the minority who do? Why is it not better, for everyone except that minority, to cap connections somewhere above what the majority of people use, and then charge people extra if they want to download a disproportionately larger amount?
FWIW, here in the UK most of the ISPs provide a wide selection of packages with different (well publicised) caps and associated prices - those people who don't use their internet connection much get a cheap package, those who have a mid-range requirement get a mid-range package, and those who want to max out their connection the whole time either pay for an expensive package or go to one of the ISPs that offer "unlimited" connections (with the expected dire performance you'd expect from an ISP who is exclusively attracting the high bandwidth users). I really don't understand the American attitude, which on one hand is "I don't want to subsidise anyone else" (for healthcare, etc.) but at the same time "I expect to be subsidised by everyone else" (for high bandwidth internet use).
What I do object to, is ISPs using the term "unlimited" to describe packages which are clearly limited. And the terrible thing is that the regulator here has said that this practice is ok. Luckily only the crap, large ISPs seem to participate in that kind of misleading marketing, with the smaller, better performing ISPs preferring to clearly label what you're getting for your money.
