Even if it were not pre-announced, the first hundred maybe two hundred who downloaded the plans/program would not be tracked, but trust me when I tell you that the entire Internet is fully monitored and most of those downloading such a program will be registered in an NSA data based and searchable.
The Gestapo/SS-SD/Abwahr and NKVD/KGB/GRU were also very thorough for their time, yet I don’t see a Third Reich or USSR around anymore.
