Sure, it's easy to see things in terms of "gimme" or "fuck you, I got mine." But there's also "we're just talkin' here, no judgement is being made. They built on a BSD library, why not submit a patch?"
It's not hard to read the judgement into the question though. Especially if you consider what the handful of popular viewpoints that show up on HN tend to be.
It's really nice when people open source things, but people don't have to do so, especially if they hope to make a little money off it.
