Code, comment out something and suddenly Active X doesn't work.
So then Windows Update, every Flash clip, Java clip, embedded movie, audio doesn't work. I don't think MS are going to hire you at any point soon :-)
re: antitrust
They lost.
The sanctions were weak because the government changed and decided it couldn't be bothered any more.
No, us.gov were bribed with free MS software. MS won, it just doesn't say it on paper. Their EULA wasn't judged as illegal either.
But that assumes all computer users are experts and know how to do this. Part of this case actually covers this because this is not and never shall be the case. Read the write up on OSNews, it explains it very well.
If something is going to store information I regard as very important, I take the time out to find out whether it is good enough for the job, and anything I can do to ensure its continuing security. Ignorance is not an excuse in the eyes of the law. For example, I don't know everything about swipe account/credit cards, but I learn that I'm not supposed to give just anyone my PIN or such details, because that compromises the security of the product. If I have a security firm add extra locks to all the ways into my house, I should be expected to learn what is required to ensure the level of security they are advertising. I can't blame the security company because I leave a key to the front door under a flowerpot.
Please note I am semi playing devil's advocate here. I think it is wrong that MS software by default is so insecure, but this is probably the way the case will be argued.
On the subject of accountability, of course everyone should be held accountable for their actions, whether they code software or whatever. However, the guidelines for responsible conduct in maintaining software security are still maturing, so cases are more likely than not to fail in this context except for the occasional extreme case.
