[citation][nom]sliem[/nom]It's not vulnerabilities, it's "exploitable weaknesses that stupid hackers found... why couldn't they just leave us alone?!"[/citation]These are not stupid hackers. Stupid hackers (more correctly called crackers or "black hats") would need the Windows source code. Windows is closed source.
How many people actually get impacted by this stuff? If you don't surf porn, warez or download cracked software does it really matter? I don't worry about CNN or Tom's hacking my computer.
I've never had a virus and actually never known any of my friends to get one. It really seems like those that do stupid things with their computers are the ones that end up getting nailed. Sounds fair to me.
