One of the presenters cited the general unwillingness of the proprietary Tetra radio systems crew to use anything besides proprietary encryption – the thing that the presenters broke in multiple ways. The European Telecommunications Standards Institute (ETSI) thought that having obscure, proprietary encryption seemed way more secure than using some open, widely vetted algorithm, even when presented with multiple weaknesses .
They also presented evidence at the talk that nation-states had previously shown a great deal of interest, and perhaps access, to Tetra-based equipment in national security contexts, so this is really nothing new, just obscure.
One of the barriers to researchers taking a look at the equipment is the extreme reluctance the hardware vendors had to them gaining hardware and software access at all.
