If anything I think this underscores the parent comment - open source is not inherently more secure than closed, it just adds another potential avenue (source code audit) to ensure security. If nobody actually audits the source, and the closed-source binary has had other types of testing done on it, it's likely that the closed source binary will be more secure.
