they are not your personal devs, and it wouldn't matter what you think, as they are developing and not you. If you want other client you are welcome to do it yourself. I can explain a lot of reasons why wazapp is better than other xmpp as mobile client, but this thread is about development. And you was asked politely not to talk offtopic here, as why it's developed is offtopic. You don't ask G+ why they do it when there is facebook. or yahoo if there is google or vice verse. It's not like they spent your tax money on developing wazapp client. If you don't find it useful, go and start developing your own useful apps. But for now you only harm the topic by polluting it with irrelevant info. Use search and you'll find all whatsapp and wazapp related topics, we have few of them on TMO, and if you, like you said, not that interesting in searching all over the TMO it's your own problem and don't make it's all other people reading this topic problem, as it's egoistic. Why do you think if you too lazy to find other topic, all active members of this thread need to be patient with you. With that approach you would never get anything you ask. Thank you and have a good day.... «I said good day»(c)
