Err… it doesn’t have to be price controls? It could be as simple as an investigation to their pricing strategy and seeing whether the markup is obscene or not. Of course what is obscene is relative, but that’s why you investigate, so that you can see abuse on a case-to-case basis.

Also, how is this level of regulatory inspection invasive? The architectural tight integration almost guarantees that the device manufacturer has a monopoly on servicing their products—it’s just that the monopoly is being allowed because it’s the kind that allows for innovation. The regulatory crackdown would be fair and justifiable.
