The thing is, most of us don't want it uncapped
I don't want to be affected adversly by 24/7 leech monkeys, so it's either a cap, or pay-per-gig.
We have a good relationship with NTL as a site, our collective voice is increasingly carrying more weight.
A letter of complaint is all very well if you have a legitimate grievance, but in this case it's futile IMO.
