There's no implied assumption about profits.

I agree that assumption is the wrong word. But do you have examples of monopolies that didn't take the profits and control the pricing of the markets they control?

Google is controlling profits from advertising and playstore sales by using Android to route traffic to those endpoints.

The profit isn't from the direct sale of an Android device, it's from the system the device is a gateway to.
