I don't see AWS doing this. They've continuously implemented technology improvements that have allowed them to reduce costs for customers 67 times in the last 10 years. The price of cloud services always goes down, not up, over time, as you're able to realize the benefits of improvements in compute power for the same cost (Moore's Law) without upgrading hardware.
