Question is, what happens if you don't have dmidecode installed? Even more interesting, what happens if you've replaced it with a fake that spews back values of your choosing? If they're bundling it, given that it appears to be GPL2, they're opening themselves to a lawsuit unless they provide source upon request.
(Somehow, I don't think they're actually using dmidecode.)
Claim that it isn't fully functional (which it isn't, for the buyer's use case), and therefore not as described?
