Is linux really more secure?

With the recent breaches at Kernel.org and the Linux Foundation several people have started asking is Linux really more secure?  Our assesment of the sitution is that any OS is only as secure as the users and Admin's make it.  A weak user password or failing to keep up with system patches both can end with the same result as the Kernel.org breach showed.  Others like Leo Leporte's Twit Network website were caused by missed updates.  So whether it's Windows, Linux or the Mac poor choices will always lead to insecurity.  Protect your data and that of your fellow users and use long, safe and secure pass phrases.  if your a system admin or Developer push hard to maintain your systems to a reasonable patch level for your company.
