Publishing work on-line IS giving it away. If you don't want that, just don't publish it online. If not, it's like singing a song at a party and getting all upset on your friends for memorizing it. Sorry, but the cat is out of the bag, and you can't tell me that _why (being involved in an open-source community and all) wasn't aware of that.
_why's taking his stuff down is also comparable to stealing/destroying things ... his work still lives on because other people bothered to make copies, but he also took down the mailing lists / homepages of those projects, disrupting the communities behind those projects, leaving nice people that invested time and resources for those projects in the dark (I don't know how much time/resources were external, but that's irrelevant).
Being an artist doesn't excuse you being dick (although it also doesn't negate your achievements). But when you're being a dick, since you're living in a society that would brake if all of us where dicks, then you should pay the price for that.
