During the Red Hat keynote speech, which was I think the best-attended 
during the ITEC show, I heard some FUD from Red Hat, with his Interbase
example of a proprietary database engine that had to fire 50 programmers,
who then were walking around with a backdoor access to the Chicago
Stock Exchange database.

I like the fact that Linux can stand without FUD. It is important to know
that closed-source systems are inherently less secure, but I think it
does not need to be _stressed_. I'm telling you there is a value to letting
the "customer" realize some things on his own.

Thus, while it is useful to point out the example of Interbase (supposedly
a secure DB solution) leaving a backdoor open, it is not necessary to
dwell on the subject in a manner which casts FUD onto the closed source
programmers. Let people figure that one out for themselves, and in this
way you have never delivered bad news. I hope that makes sense.
