Not to stick up for Microsoft as they certainly have done many seemingly underhanded things over the years, but with 76,000+ employees my guess would be that this was carried out by a single individual and was NOT authorized or condoned by the Company.
I don't think anyone or any Company should be tarred just because of the actions of an individual unless they either knowingly allowed it to happen or did not take at least basic precautions to prevent such things.
These files though were created over 5 years ago (back when few Companies even knew or looked for internally cracked software or tools)
I would venture to say that such an action by an internal employee now days and not be found would be close to impossible (as it should be).
