The default text communication application on the phone silently converts messages into a proprietary format, and it only barely interoperates with SMS. If it came with some kind of proprietary voice system that only barely worked with Android phones, people would be out with pitchforks. I don't have a problem with apps doing proprietary things. I do have a problem with the default app pushing you and everyone you know to buy an iPhone so you don't have to deal with the screwed up SMS integration. They're abusing their prevalence in the marketplace by making their messaging incompatible with others. What if Facebook made a phone OS and made the default messaging app WhatsAppPlus, which can only be accessed from a Facebook phone, would that not be an issue?
