You're being highly obtuse. Universally everyone understands "raising prices" to be - "raising prices without any customer action". As in you consider your options, take into consideration pricing, design your architecture, you deploy it, and you get a bill. Then suddenly, later, without any action of your own, your bill goes up. THAT is raising prices, and it is something AWS has essentially never done. What you're describing is a situation where a customer CHOOSES to upgrade to a new generation of instances, and in doing so gets a larger bill. That is nowhere near the same thing.
