I don't remember paying even the $1 to them ever and I've been using WhatsApp for a good few years. Every time the expiration date approaches, it automatically gets pushed away. Either they were just giving away subscriptions intentionally or I'm just one lucky bastard.

I'm a Mac guy so I can't give brands but I've been seeing those tablet/computer hybrid things (not necessarily Surfaces) at conferences where I'd have seen 99% Macs before.
They are the dominant player in this market, I simply can't understand why they didn't crewed it already.
I can only speculate: it's because WhatsApp is giving them an always-updated social graph of a billion people right now (including inferred information on people who, like me, didn't install the application but whose numbers are in the contacts books of people who did it) and crossing this information with FB data brings more revenue than anything they can do with WhatsApp itself.

Like with almost any open source project nobody promises you anything. But it's not framework, you don't lose much by not using it and you don't have to rewrite your code in case it would be abandoned.
yes I realise that I'm looking a gift horse in the mouth, and I love git(hub), but I'm just pointing out that "(github.com)" might just be a net-negative marketing point for people looking for robust software.
