Pink Floyd star Roger Waters has criticised actress Scarlett Johansson over the controversial partnership with SodaStream which ended her long-running association with Oxfam. The Avengers star hit headlines last month (Jan14) when she was criticised for becoming the face of the Israel-based drinkmaker which has factories in the contested West Bank region. The deal clashed with her work as an ambassador for Oxfam, which is "opposed to all trade from Israeli settlements", and Johansson subsequently stepped down from her role with the charity. Waters, a fierce Palestinian supporter, has now revealed he has written a number of letters to Johansson since the story became big news. In a post on his Facebook.com page, the rocker writes, "In the past days I have written privately... to Scarlett Johanson (a couple of times)... Sadly, I have received no reply... I met Scarlett a year or so ago... you could have been forgiven for thinking that here was a young woman of strength and integrity who believed in truth, human rights, and the law and love... A few years down the line, Scarlett's choice of SodaStream over Oxfam is such an act of intellectual, political, and civil about face, that we, all those of us who care about the downtrodden, the oppressed, the occupied, the second class, will find it hard to rationalise." Waters also admits he can't understand why the star chose to defend the SodaStream deal after the actress insisted the company is "committed... to building a bridge to peace between Israel and Palestine, supporting neighbours working alongside each other, receiving equal pay, equal benefits and equal rights." The musician adds, "Scarlett, I have read your reposts and excuses, in them you claim that the Palestinian workers in the factory have equal pay, benefits and 'Equal rights'. Really? Equal Rights? Do they?... Scarlett, you are undeniably cute, but if you think SodaStream is building bridges towards peace you are also undeniably not paying attention."
