Megaupload wasn't really good in preventing misuse, from what I've heared. They did not use checksums to identify violations, so if you want to see your file gone from MU, you will have to track down every single download URL. Other file hosters do this in a different way.

Another doubtfull thing is that Megaupload actually paid money to people with a lot of downloads. I don't think they checked if the content was legit. And Kim "Dr. Kimble" "Dotcom" Schmitz isn't really known for his willingness to stay within the borders of the law.

I don't like the thoughts behind PIPA and SOPA, this goes way to far. But closing MU has not much to do with this.

And, by the way, I doubt that that much of the content is company based stuff. Companys usually need to controll who is downloading what, or they want statistical data who's using their stuff. Megaupload wasn't made for a corporate environment.

Just my two cents.
