So it's not at all about privacy?
That's interesting. But it makes sense, I suppose.
It's just the vocal minority that push privacy in WhatsApp. But it is good to see Facebook supporting private communication. Apple and Facebook, who would have thought?
In the case of Apple it's much more obvious, when most of your revenue comes from hardware (and now also 'services') you don't have to mine your user's data for ads.
WhatsApp introducing Signal-based end-to-end encryption after it was acquired by Facebook was definitely surprising. I guess they can always switch to on-device profile creation :p. I trusted Whatsapp as a separate entity (low costs, yearly fee). Facebook, not so much.
"Since the majority of WhatsApp users in Brazil have access only to low quality internet connection"...
Not unlike the shitty situation in the US.
Even if you're offline and send a message, it stores it locally and send it when connection becomes available.
Since the majority of WhatsApp users in Brazil have access only to low quality internet connection, this becomes a major issue.
