ISPs don’t even pay for the majority of their bandwidth, they get it for free via settlement free peering. Where’s the rebate going to come from that? On the fraction of bandwidth ISPs pay for, the wholesale rates are less than 5 cents per Mbps. On average a subscriber uses a few Mbps on average. Would 15 cents per month really motivate you to go all in on IPv6? On average bandwidth costs for an ISP are single digit percentages or less of all costs. Even if their wholesalers would fully discount all their IPv6 traffic (why would they do that?!) there’s only so much there to work with.
