Apple absolutely does follow this strategy: it's not presently very profitable to be a supplier of small electronic components, or a contract manufacturer, or an app developer, or an Apple retail store employee. At least in the case of app development, Apple puts significant effort into making their dev tools powerful and their development experience easy, with the goal of bringing in as many devs as possible and keeping the market commoditized.

The difference is that most of Apple's complements are B2B suppliers and so are rather invisible to the general public, while many of Google's complements were formerly consumer-visible markets. So it's much more obvious when Google turns the web browser or ISP market into a commodity than when Apple turns the electronic supplier marketplace into a commodity.
