Open Source Security Confidence Idealism

According to a few news articles, the general public has taken notice of all the recent security breaches in open source software. From the article: "Hackers have shaken the free-software movement that once symbolized the Web's idealism. Several high-profile attacks in recent months exploited security flaws found in the "open-source" software created by volunteers collaborating online, building off each other's work."

While it's true that open source means you can review the actual code to ensure there's no data-theft, loggers, or glaring security holes, that idealism doesn't really help out most people who simply don't have time, or the knowledge, to do it. As such, the trust is left to the open source community, and is that really so different than leaving it to a corporation with closed source?"
