Mark Hamill (aka Luke Skywalker) used Twitter yesterday to announce that he is publicly demonstrating his opposition to Facebook’s stated policies to allow untruthful political ads by deleting his account on the social platform. Mr. Hamill’s protest follows similar actions by actor Sacha Baron Cohen and others. “So disappointed that Mark Zuckerberg values profit more than truthfulness that I’ve decided to delete my Facebook account,” Hamill wrote in his tweet.
