It's not a fuzzy logic rice cooker. I've used [sic] because it's an incorrect characterization of the item.
I agree with your marketing observation. Maybe they could have called it sophisticated logic (or something like that)? The history of fuzzy logic (which was cool) could be replaced with stories of sophisticated problem solving.
[Sic] is used to indicate that a linguistic malformation or variance within a quotation is being intentionally reproduced from the original source, thus preventing the reader from thinking that the disfluency was newly introduced in the act of transcription. Using it to express your personal opinion on the perfectly grammatical and accurately spelled content of the quotation is terribly confusing.
