Here is the article about TPB taking over the distribution.
A few days after the blueprints for the world’s first printable gun were published online, Defense Distributed has been asked by the State
Department to pull them down, citing possible arms trafficking violations. The blueprints, however, are still available on The Pirate Bay and many
other file-sharing sites, which adds a 3D chapter to the IP enforcement debate.The Pirate Bay says it welcomes the blueprints and has no intention of
taking the files down.
In late 2012 the 3D blueprint website Thingiverse decided to ban 3D gun designs, citing their terms of service which clearly prohibit files used to
Enter DEFCAD, a site dedicated to hosting designs that have been banned at Thingiverse. Namely, the entirely printable 3D gun design which clocked up
more than 100,000 downloads within its first two days of release.
This did not sit well with the Department of State Office of Defense Trade Controls who kindly requested that DEFCAD remove the availability of the 3D
printable gun documents, enthusiastically named “The Liberator,” citing a possible violation of International Traffic in Arms Regulations.
In the letter from the State Department, which can be read in full at Forbes, the Government explains that it wants to review whether the designs are
in compliance with arms export control laws.
While the attempted censorship of the 3D gun blueprints may come as no surprise, the popularity of these files is a vivid example of the daunting task
faced by those charged with censorship of information.
While DEFCON promptly complied with the request to remove access to the design, it was shared so widely during the short window of availability that
it is now virtually impossible to prevent any further distribution. Currently, there appears to be several torrents available for the design at The
Pirate Bay and the site informs us that these will not be censored.
“TPB has for close to 10 years been operating without taking down one single torrent due to pressure from the outside. And it will never start doing
that,” A Pirate Bay insider told TorrentFreak.
