A Washington District Judge has issued a Nationwide Temporary Restraining Order (TRO, also known as universal injunctions) to prevent DEFDIST from distributing the DEFCAD files. Given that at least one SCOTUS justice has commented on such injunctions in a fairly derogatory fashion (see Justice Thomas' concurrence, starting on pg 47 of the PDF), it seems likely that such injunctions are on thin ice... But since the TRO only mentions DEFDIST, and pretty much all the other interested parties are happily distributing the files (See codeisfreespeech.com and fosscad.org, among other places, and note that some of these places only provide links to Magnet URIs for torrents or links to an external download mirror), it's not likely going to have much effect, even if SCOTUS doesn't decide to slap it down ASAP. Especially since at least a few are going to respond to any such TRO with "Make me" at which point the judge either finds out just how little power he has, or the case gets fast tracked to SCOTUS. The Streisand effect is in full force.
Links to the magnet URIs for the original DEFDIST mega pack (the one that predates the State Department cease and desist, the settling of which set off the current to do), and the current FOSSCAD mega pack can be found on the Gun Related Downloads tab. As Mr. Universe said, "You can't stop the signal."
