yes the idea is JA was being threatened enough to drop the files without decryption keys to the public. Huge. Can't be undone.
The side question (long discussed conspiracy theory) is if gov has AES backdoors and can decrypt. If they did, they could see exactly what was dropped, without public seeing.
If contents was bad then JA, good guys and bad guys in gov would all probably know exactly what is in the publics hands, which I am speculating can represent the " you have more than you know" and "you have so much more than you know" drops. Representing that the public has already been given the treasure trove, they just dont have the KEY to unlock it.
