Nice examples. One-sided though. All software has bugs. You prefer
security through obscurity (closed source, and you have to _trust_ the
vendor of it). But there are numerous security issues with closed source
M$ Windows system. Of course, you would prefer closed source example UNIX.
Here it goes: SSH (as opposed to openSSH we all have thanks to OpenBSD
project). There was an awful security hole in it about 13 years ago and as
sshd daemon runs by user root, we were just waiting if stray root just
will walk into our Solaris boxes. Waiting for parch from system vendor and
simultaneously compiling openssh as a replacement. Those of us who had
majority of boxes under Linux (hence with openssh that wasn't vulnerable)
had less trouble...

I guess, you go you to your church, and I will go to mine. I do not
consider "security through obscurity" a security. I prefer not to wreck my
brain thinking "to what extent can I trust this corporate vendor". I
prefer the code put out into open so everybody can review it. I doesn't
mean that open source code will be audited diligently. But the fact that
it can be gives the best reassurance for me. I do join that clever person
who said "security only can be in open source".
