> One of nbn™'s most intractable problems is how to grow its monthly average revenue per user (ARPU)
Increasing ARPU is not an intractable problem. Labor had the solution: usage based charging via CVC. Those who use the network more pay for it (like tolls on roads and fuel excise) avoiding the tragedy of the commons. The coalition have cleverly thwarted this by first reducing CVC from $20 to $8 and then bundling CVC into plans.
RSPs offering unlimited data plans have little incentive to offer faster plans because those paying extra for faster plans are likely to be more demanding and capable of monitoring performance.
