Open Source is a process for overcoming the traditional weakness of the commons. Clearly did not work for OpenSsl. The shallow bug conjecture is more of a statistical notion, not something to bet your security on.
When you read Locke and the idea all that matters is equality before the law now seems quaint in practice. Equality of outcome, equality of property, equality of education, etc wasn't a guarantee. And that makes sense, until you realize how equality before the law is impossible without some balance of the other equalities.
