Yes, to the extent that every chat app is a clone of every other chat app, WhatApp is a clone of BBM. Other than that, what exactly are the similarities?
The whole point of WhatsApp is having a primary key that is your phone number. And they launched on literally all kinds of OSes that developing countries were using, including Symbian as late as 2012. So please tell me, how exactly is a service where you can message each other by their phone numbers and that was probably supported on the most number of platforms for its time "exclusive" and "in-group".
Sorry but you don't seem to have any idea what you are talking about.
