What I don't understand is that effectively for me, and everyone I know, Whatsapp is indeed free. Everyone started using it despite the "1st year free, after that pay up" and every year since we get a message saying like "we extended your membership for another year, please consider paying though". I'm not sure if it's different in other countries but from where I stand there's loads of people using whatsapp and not paying a cent for it.
