That line at the end there...I'm not really sure what to make of that. This page is aimed at potential game developers, not the public. The way I see it, they're just annoying developers who take the Ouya seriously. I mean, I DON'T and I'm impressed at Valve's cojones, it just seems very out of character for them. They're usually much classier than that.
EDIT: Since this isn't as apparent to everyone else as it is to me, scroll down to the bottom of the Ouya Kickstarer, just above the FAQ. You'll see what I'm talking about. Sorry 'bout that.
