It's a chicken and egg problem tho, whatsapp doesn't support smaller platforms, and smaller platforms can't grow without app support. I remember that the uptake of Windows Phone 7 and early versions of 8 was pretty low partly because whatsapp didn't support that OS.

WhatsApp has reduced the number of platforms that they support, they had a KaiOS app but disabled it last year.

		I know, but my comment was more along the lines of Windows Phone 7 coming out in 2010 and whatsapp being available a year later, and of whatsapp not having a native app for Sailfish
