Funnily enough, Hugo has zero with the New York-based publishing industry since Hugo nominees are nominated by World Con attendees and voted by the next World Con attendees. Anyone who can spare some cash for a supporting membership can nominate and vote as they like.
If you were talking about the Nebula awards, however, you might have been right.
Especially at this age, publishing a book via Kindle is trivial and if a so-called "wrong type of person" writes a good book, he will be able to sell it, or made it read enough to be nominated. The award to related-work went to a fucking blog post, and rightly so, it was a well written article related to SF. Three of the stories who won were "printed" on Tor's web site.
Any idiot who can design a web site and gather enough readers who will like it and nominate it in the next World Con has the chance of winning the next Hugo, no conspiracy required.
