Just spit balling here but didn't Microsoft get sued for Anti-trust along the lines that they packaged their software into the operating system they sold to control the market for word processors, spread sheets etc?
I see what you are trying to get at. The case against microsoft was basically that they created their software to be incompatible with other operating systems, as you said effectively creating an impossible-to-match competitive advantage.
What ew is saying might be closer to the complaints levied against Wal-Mart. That because of there preeminent place in the marketplace they can dictate to manufacturers certain price points, product characteristics, etc, that wouldn't arise normally in the market. Creating an unfair (but not impossible to match) competitive advantage for outsiders.
Apple, is dictating only content as far as I know. His complaint is more similar to Wal-Mart or another retailer deciding not to sell CD's with explicit lyrics. Artists and recording studios representing them of course complain that they are being unfairly closed out of the market. Of course, if they chose to make a CD without explicit lyrics (which most have) they will get the sales they are missing out on. Just like the developers could in this scenario.
