This is an interesting perspective however only the most extreme examples given are convincing enough to be as truly adversarial as the author implies.

Using the articles very own examples, hardware seems to be attempting to commoditize software, and software seems to be attempting to commoditize hardware, the chain is bidirectional and long, there seems to be no clear rules. In the example of Sun and Ximian, it can be viewed as commoditizing or directly funding a non existent yet required comunterpart due to lack of in house expertise.

I suspect the reality of the majority of less visible chains of compliments are closer to symbiotic than parasitic - that intentional and extreme commoditization are the adversarial exceptions which are so large and monopolistic as to bias the landscape... even then as other commenters point out, those relationships don't appear to be sustainable long term, due to longer term negative side effects or a changing landscape.
