A Potential Problem with Intellectual Property Rights, Part II

Besides Mark Kurlansky, there's another author who tried to control what people think as a result of his book. I earlier mentioned that Horton Hears a Who could be thought of as anti-abortion. For some reason, Dr. Seuss was opposed to that interpretation:

Somehow, Geisel’s books find themselves in the middle of controversy. The line from the book, “A person’s a person, no matter how small,” has been used as a slogan for pro-life organizations for years. It’s often questioned whether that was Seuss’ intent in the first place, but I would say not: when he was still alive, he threatened to sue a pro-life group unless they removed his words from their letterhead. Karl ZoBell, the attorney for Dr. Seuss’ interests and for his widow, Audrey Geisel, says that she doesn’t like people to “hijack Dr. Seuss characters or material to front their own points of view.”

If William Shakespeare were alive today, would he sue to prevent philosemitic interpretations of The Merchant of Venice?
