Is this OK? Aljazeera article refers to GEJ as Badluck Jonathan

The article is an opinion piece by Solomon Ayele Dersso, a legal academic and analyst of African affairs who regularly writes on African issues. He is head of the Peace and Security Council Report at the Institute for Security Studies, Addis Ababa office. He wrote an article titled Badluck Jonathan and Aljazeera posted it. Is that not offensive?
