Valve engaged in price fixing by preventing publishers from selling games at a lower price than other platforms. They're committed to openness to the extent that it helps them undercut consoles, but not to the extent of allowing others to undercut them. Selling cheap open hardware seems like classic "commoditize your complement" tactics. (Especially since most gamers will probably just buy from the steam store when using their hardware anyways...)

I'm glad valve exists, but they are not a charity and do not need your sympathy.
