I sent a stinging message to Whatsapp.

Dear Sir,

The essence of Whatsapp's attractiveness as an IM software is its cross-platform nature. Hence I cannot understand your reluctance to port to new platforms like Meego-Harmattan (N9). Your policy strikes at the heart of Whatsapp's popularity. With the rise of free IM software like eBuddy, LiveProfile and Chat-On which are less selective about porting to new platforms I'm afraid the time will come when Whatsapp's dominance will be demolished.

Regards,

No reply from them. Maybe they are stewing in their arrogance.
