Is designing a website for a company that facilitates the sale of pirated books without the owners' permission considered participation in sin?

Your work in designing a website for a company is not related to the company's unauthorized copying of books. Therefore, there is no sin upon you in designing the website and receiving payment for it. If you are able to advise those in charge to stop copying books whose owners prohibit their reproduction, then do so as an act of enjoining good and forbidding evil.
