BPI's short video explainer of the entropy flaw (proper key space as one atom in two billion galaxies versus the affected firmware's much smaller pool), with sympathy for victims, a note that BPI team members were personally affected, and policy reflections promised. The held artefacts are the element screenshot and text; the video itself is held via gallery-dl.

This post is registered as evidence and has a locally held capture. The original remains the canonical publication.
