I've never seen commodity used to refer to products from the same range, from the same manufacturer. Basically, you've just claimed that anthying that isn't a hand-made one-off creation is a commodity, massively weakening its actual meaning which you're supposed to be defending from misuse.

Commodity isn't a totally binary state, even with fuel or coffee you get variations in quality and brand. It's just that these factors do not dominate. At the other end of the scale Apple is trying very hard to stop iPhones becoming commodities by stopping cross platform Flash apps, not allowing access to iTunes etc. which prevents similar devices from other manufacturers being swapped in without disruption. Saying you want to move your complements down the scale towards being a commodity doesn't imply that they will end up at the extreme, just that they'll have less market power over you, the definition of commodity often being given as an item being sold or bought at a market rate.
