An interesting observation; but one I would take issue with.

When considering the trust that one can place in an operating system, 
two issues immediately spring to mind: the trust one can place in the 
vendor's staff not to leave trapdoors in the O/S code (deliberately or 
otherwise); and the quality of the testing that has been applied to that 
O/S.

On point one, I would trust LINUX (or indeed any other freely available 
and widely used source code O/S) better than any non B class certified 
commercial product because there is sufficient public scrutiny of the 
source code to cause any such errors to either be eliminated, or at 
least be advertised.

On the second point, I would hazard a guess that LINUX et. al. have 
probably had more O/S testing (as opposed to usage) applied to them than 
most commercial O/S.
