It’s not the same legal conception of intermediary liability as with online services, but I’d argue that it’s an extension of the same idea. The manufacturer has somehow been conceived as a legally vulnerable intermediary between the user and the printed/milled product, and the legislature is attempting to force them to interfere in the manufacturing process, with the threat of liability as a club.

This same trend is happening all over, from banking to communications to manufacturing, where private industry is deputized by force to police consumer behavior, without consumers receiving any of the usual protections provided by the legal process. We’re effectively witnessing the construction of a privately mediated police state.
