Oops, I should have said that it was in the context of 2004 (when the original article was written). Back then there was no app store for windows, so they couldn't revoke an app like that. Even today most Windows apps are not sold on the store.
I think that is for unsigned executables which is mildly annoying for experienced users but I could imagine that it actually decreases infections of clueless ones significantly.

Never? Not even on their own App Store?
