I think you're confusing two largely-unrelated issues. Whether products are developed according to what users want vs what builders want has almost nothing to do with bazaar vs cathedral. Indeed, many bazaar-style projects (the linux ecosystem in general, gimp, etc) are almost cautionary tales about "builders creating what they want for their own niche purposes and if anyone disagrees they're free to fork off".
