Market pressures take care of that when they exist. Networking is a pure commodity business, you can squeeze a lot of cost out of it, but in the absence of competition the providers get fat, lazy and rich.

Once you deliver the fiber, the marginal cost of increasing port speed is a rounding error as you do routine infrastructure refresh.

Where I work, we’re increasing many wan links to 10Gb because the cost is marginal at scale. In some cases, it can save money versus an older slower tech!
