And it makes sense. If you publish some state-of-the-art algorithm then you're basically helping your competition, and you don't get anything back from them. So you publish bare minimum in small articles on your website, only to gain people's/investors' interest, and just hope that you didn't share too much. And it'll always be like that, unless the root cause changes - intentives. And the main incentives right now are money and power.
