people who share their source code do not owe you anything
A-fucking-men
The entire controversy that redis experienced and probably a bunch of other projects, I find to be ridiculous. We don't live in a world where everyone can afford to try to build a business upon freely available code they wrote and have it fund another bigger business. Sure, some people are content with "free publicity", or being the sole maintainer of an immensely important project that generates millions for mega-corps.
A great talk, but unfortunately, probably too long for the people that should see it.
