Low Culture, High Tech: Happens an awful lot, due to the absence of any Alien Non-Interference Clause, and the common interpretation of general free trade statutes by free traders as “can (and will) sell anything to anybody who wants it”. If they don’t read the manual (or, in many cases, the encyclopedia) – well, at least what happens subsequently is unambiguously their own damn fault, and they haven’t a leg to stand on if they come back to you in the future to bitch about it, unlike the problems that arise if you try to play regulator to their technological development.
(More sensible low-tech societies go out and hire some professional uplift consultants to avoid this biting them on the ass too hard.)
