Reminds of of this case, which happened to famous CS blogger Scott Aaronson:

Australian actresses are plagiarizing my quantum mechanics lecture to sell printers: http://www.scottaaronson.com/blog/?p=277

tl;dr of the article: Someone created an Australian commercial for a printer. Two models are talking physics/CS to each other, and the tagline is "A more intelligent model". The models' script is copied from one of Scott Aaronson's lectures.

I think he ended up contacting them, and getting them to donate $5,000 to a CS foundation (instead of sewing them for copyright violations).
