They get the issue and some press without the risks of being locked up by the Feds. Not sure I blame them.
IMO, the WikiGun project was always more about raising awareness and with the story coverage I'm sure there's a lot of people who are now aware of the concept of "printing a gun", not now, but for the near future when these devices are sufficiently commoditized, than it was about actually producing guns.
It's kind of like saying all personal PC architecture would always be based on the Altair because it was the first kit guys were playing with at home in their garages and basements back in the 70's.
Heck, it's not even really about GUNS, it's bigger than that. The idea that someone may someday be able to make stuff at home to a high quality industrial standard that Uncle Sam want's to regulate, whatever it may be, is the bigger picture here.
People want to see a clear progression of succession inventor-A through to ubiquitous end product B. It does not work that way. Merely getting the idea out there in the general population is what's key. It's like the embryonic stateless digital cash idea. It doesn't matter if BitCoin is the one that does it, or succeeds. It's just the idea that's important. The marketplace will take care of determining which one is best.
It was once said "The Revolution will be Televised".
We're past that. Now it's: "The AnCap/Libertarian Minarchist future will be digitized."
