Would you guess that this quote is from the early 2000s? This guy knew things decades before others.
Microsoft also knows that real security is not cost-effective. They get whacked with a new security vulnerability several times a week. They fix the ones they can, write misleading press releases about the ones they can’t, and wait for the press fervor to die down (which it always does). And six months later, they issue the next software version with new features and all sorts of new insecurities, because users prefer cool features to security.
