Whatsapp suddenly became free to download for iphone users. However, as an android user we've still got a timer, so we still have a yearly subscription fee unlike the iphone users. I've noticed people have started to give the app a 1 start rating to protest. Pretty good strategy if everyone protests. If not we can move to a free service like Kakao Talk (for example. My personal preference over Ping Chat, and the gazillion other programs out there).
