Very good article--especially this comment:
(22) With Linux and other free software there is little reason to fear the existence of backdoors, in large part because all of the source code is available for inspection. A backdoor is a secret method for obtaining remote access to a computer. There is a (not unjustified) concern by many foreign governments and corporations that back doors have been covertly inserted into proprietary software that could allow the software developer and agencies of other governments to snoop into their most confidential data.
I have little to hide. Much of what I do on a computer is posted on forums that can be read by anyone in the world.
Anyway, I can't help it--I do not completely trust Microsoft and always wondered if they (or any other company--Sony comes to mind) might be doing something like this.
