First I want to go on the record as saying I think that Kim Dotcom is a huge douche. That being said, he's our douche.
Some people have theorized that the real reason for the Megaupload raid was that he was about to start his own music label, which, if you think about it, could have revolutionized the industry. It's important to recall that many big name hip hop artists frequented the site, and there's no reason to believe he couldn't have been successful.
It remains to be seen if he could even get the site as popular as it once was if it was resurrected. Internet sites don't have an amazing track record of that. The internet is a fickle mistress!
But I hope he succeeds and destroys the entire existing recording industry by outcompeting them.
