I suspect that once the SAFE network is live, you could pretty easily upload a dozen videos, and write a immutable webpage script that publishes them one at a time over the course of 12 weeks.
Submitting these items to the network would be irrevocable – nobody could prevent these from being published – No court order, no bribery, no bullet to the head… Nothing could stop it.
They also could’ve uploaded the footage through a torrent, which would make it practically immutable as well. Looks like they wanted to publish it only on TV or some other controlled channel, for whatever reason.
