Sure, I'm just saying in reality it's not as ideal as it would seem. You're not going to get thousands of new qualified people reading every codebase every year, things will inevitably slip through the cracks, and at a guess open-source lines of code probably have fewer people reading them net than all currently maintained proprietary software, just because there is so much vastly more open source software these days.
