If you think that lawsuit is bad, check out the followup, as the Faulkner estate also went afterthe Washington Post:
The second lawsuit, filed Friday, was against the Washington Post and defense contractor giant Northrop Grumman. Why? Because Northrop Grumman ran an ad in the Washington Post that quoted (with attribution) a single sentence from a Harper's article that Faulkner once wrote.
The ad, which ran on July 4th, 2011, included: "We must be free not because we claim freedom, but because we practice it. -- William Faulkner."
