Maybe pulling things down is "comparable" to stealing, but it's not the same. And the extent to which external resources were part of his work is not irrelevant. There's tons of gray area here that's being glossed over.
Zed (and other posters) seem to have a view of the issue that lacks nuance. "He abandon us, he must be a dick." I'm not sure know why "dick" is the only name Zed et al have for _why. Besides the fact that the word is grating and low, it is bad form and, frankly, a little immature to use insults like that, especially when you don't know the whole story. The HN community both eulogized and demonized _why too quickly. Maybe it makes sense that hackers only think in binary terms and pass such stark judgment.
Look, I'm disappointed that _why is gone. There have been good points made on this forum about people who depended on the mailing lists, etc. And we can speculate ad-nauseam the causes for his disappearance. Personally, I thought his work was touching. As I discussed earlier, I also view him as an artist, with motivations that I think are very different from those of a typical hacker or engineer. But because we don't know the whole story, any judgment is based on speculation. And so I must give _why the benefit of the doubt here (and, clearly, defend him a little).
It's wrong to judge _why as Zed and others have, 'nuff said.
