I worked for a major UK ISP for a while, about 1% of customers fully utilise the connectivity they get. One of the bigger issues for us, was getting enough backhaul capacity from the wholesaler (BT OpenReach) at smaller regional locations. Also we were obligated to pay for multicast traffic on a delivered bandwidth basis per user, even though multicast isn't unicast and so the overall network traffic was only individual on the last mile! I have absolutely no issue with contention as long as it doesn't substantively affect my experience. Some users get very upset about "ping times" but there's also evidence that the numbers in games aren't actually practically useful to a point (unless they're objectively large). ISTR one game developer fudged the ping numbers to stop people complaining about competitiveness.
