WhatsApp Messenger is a proprietary, cross-platform instant messaging application for smartphones. In addition to basic messaging, WhatsApp Messenger users can send each other images, video and audio media messages. WhatsApp pride their selves of being cross-platform, but is that really the case, when the MeeGo-Harmattan/N9 Community is unable to use the WhatsApp Messenger?
MeeGo-Harmattan is considered, somewhat, a dead platform, as Nokia have no plans to release other devices sporting that OS (unless stated otherwise in the future). However, the Nokia N9 has been highly appraised by online tech journals and its sales have been off the charts wherever it was made available (as reported by various technology blogs, mobile operators and third-party retailers). We are not making this petition to express dissatisfaction or hatred to WhatsApp whatsoever, but to let them know that we have grown accustomed to their program, and we would love to have it on our Nokia N9s.
WhatsApp, even if we are considered a 'small' community when compared to iOS, Android, or Symbian, we still want to be considered a part of YOUR ecosystem. Let us not forget that using Qt as a development platform, you can distribute WhatsApp not only to Symbian, but to the rest of the Nokia communities too (MeeGo-Harmattan and Maemo). You have a loyal fan-base who would like to see your application on their smartphones, to make their experience more intuitive. So, the question is not "why to make a Nokia N9 version?", but rather "a lot of Nokia N9 owners want this and love our product, so WHY NOT?".
