Yeah, because a piece of paper pinched out by the government is going to stop people from sharing information.
3D-printed gun blueprints are on the Pirate Bay (for example). They're hosted on overseas websites. When the first story about the government forcing the author to take down the DefDist package came out, I made copies and posted them to six different domains I own (for example). If this regulation passes, I, and I'm sure plenty of other people, will step up their efforts to spread such files wider and wider.
