Ok lets look at this from a different side.

What if someone puts a root kit into an opensource application really
burrys it, but the thing is it is there opensource app. Like If i made
Wee robby's windows emulator, and I still some stupid root kit code in
there and you install it and you use it not knowing that I place a a
root kit in there well your just a little SOL, someone would find the
code eventually but not after I infected people with this thing. That
is the problem with Mac and windows right now is there are too many
users who trust everything they read and have this I think i should
install this attitude and next thing yhou know the machine is infested
with rootkits, spyware using rootkits and god only know what else. All
I am saying is that I believe that if 90% of the computer using public
ran linux or bsd or any kind of *nix that they would stupidly hand over
the root password to install something and the next thing you know they
have a linux that just as unstable as windows can be.
