Complaining that a business is charging too much money for its product is silly, if everyone is willing to pay that price. The central insight here is that there is no morally correct price for something, there is only the market price. Goods and services don't have "correct" prices, there is only what people will pay.
If you are willing to pay, saying they are charging too much is just wishful thinking.
