      anyone who is writing software can attempt to put backdoors in
      it, but the real key is what privledges the software has when
      it is running in its production environment. It is very
      unfortunate that PC operating systems like windows get used
      in production environments, because whatever code runs on them
      has acccess to everything on the PC - it could for example
      delete all of the stuff on hard drives, talk to comm ports, etc.

      Under the Unix OS (and all its various spawn) most software
      can run without privledges, so that even if the developer puts
      in a backdoor or other bad code, that code may not be able
      to do anything bad because it will try to do something, and the
      OS will simply deny it access.

      Unix, of course, was a Bell Labs product, and was much used in
      the phone network and related activities long before most other
      businesses. So, if you use the right tools, and software, and
      your brain, you can be somewhat proof against this kind of thing,
      but of course nothing is perfect.
