Honestly, if the machines were that profitable then the companies making them would just keep them and mine on their own, as it would be more profitable than just selling the hardware.
This actually isn't totally true, since cryptocurrencies rely on several kinds of trust, and one of them requires that no single entity controls the mining. So it can sometimes be in the interest of a mining equipment manufacturer to even sell mining equipment at a loss, if the manufacturer also mines.
