Are giant open-source projects like Chrome, Firefox, or FreeBSD cathedrals? Unlike bazaar poster child Linux, these projects mostly control their own roadmap and releases, without many competing distributions.
So at the end of the day I personally feel that bazaar is the best set of training wheels invented but quality ultimately gravitates towards cathedrals. Both parties do benefit a lot from each other, so mutually benefiting, implicit agreement is at play here, which is something "A Generation Lost in the Bazaar" piece fails to acknowledge.
