That's true, and I agree to a point. But, I think they wanted to nail the "You don't even need a dongle" part of it. Because none of this is enabled by Flipper or a dongle. A handful of components you can get from a broken radio suffice. There's nothing magical or beyond reach making this attack possible. You don't need custom chips, or a long logistics pipeline to enable it. You don't even need a company to produce anything specific. The from-scratch demo they posted hammers home that working from nothing you can do this in an afternoon with tools you can get at Walmart and it's well within a high school student's abilities.
