[But to reply to your metaphor: I certainly hope
you're not
intending
to compare Microsoft software favorably to Wikipedia contributions.

like
Linux, BSD, or OS X where massive gaping security flaws aren't
inherent in the system.]
Massive gaping security flaws aren't inherent in Wikipedia in regards
to preventing vandalism? That's news to me.
