It's totally relevant to my point but let's ignore that for the moment. Do you agree with the original comparison? Do you think the US is like free software? Or is the US more like Open Source? Is the US BSD or GPL? Is RMS the president of free software? China is a pristine cathedral right?
Do you realize that things can be alike while not sharing every single characteristic in common? If we held that requirement we could only compare two identical things, which would be pointless.
It would be in the sense of a greater emphasis on centralized planning compared to the more organic growth of many actors pursuing their own interests in the US.
If you're going to complain that China doesn't have stained glass windows and isn't a building made out of blocks of granite, then you've missed the point.
None of those things are inconsistent with the central planning / organic growth dichotomy that is what the cathedral / bazaar analogy is getting at. It's not superficial, it's just making a comparison of one specific aspect of the two cultures, not trying to be a comprehensive model that explains every single thing about each one.
