Where in the article does he call for revolt?
He doesn't. The author of the article, and the headline writer, have made a false accusation that is defamatory in nature. The shop owner has called for political activism, not for revolt.
I'd sue the publisher and the author for defamation. The article is meant to be a serious news piece, not parody, and it is making a serious accusation, knowing that the accusation is false.
