In the context of machine intelligence, I reckon that means open-source software.

I figure, if you try and keep your source code secret, only fools will trust you. More to the point, competing organisations - who are more willing to actually share their results - are likely to gain mindshare, snowball, and succeed first.

Of course, it doesn't always work like that. There's a lot of secret sauce out there - especially server-side. However, for ethical coders, this seems like a no-brainer to me.
