I find it perplexing that the main criticism of WhatsApp is that it's owned by Facebook.
@pcrock Yeah, I find that annoying too. It's just an app that *enables* people to communicate with each other. Why should it be a cause for exclusion, just because it's owned by Facebook?
So, what I have resorted to do is, I *still* have WhatsApp, with the minimum set of permissions I can grant:
* No Camera
* No GPS
* No Storage
* No Contacts
This means I cannot initiate conversations with people I want to talk to, but I can only continue from previous conversations (or they have to initiate them first). I'm perfectly fine with that - as in, I'm not itching to talk to them *only* over WhatsApp when I can do with alternative medium of communication just fine.
