no, the people who regulaly go over the fair usage cap at peak times is about 3%.
People either spit their dummys out over bad pings or download caps, I dont see the problem? If you want more why not pay more? Its not exactly hard downloading during offpeak hours either.
because you've paid for something that says Unlimited in the title...Why not just say no more than 50 GB per month?
if you say unlimited then just give a vague fair usage, which means basically we've over sold our outdated networks and now can't give the service they promised, then you should be made to give unlimited, or at least a straight definition of what fair use is.
