Tracking the WhatsApp habits of random smartphones
I've been using WhatsApp for years, reluctantly since it is the de-facto SMS standard in my country.<p>I will never, ever, understand the "online" status feature. It is ridiculously invasive and cannot ever be turned off or even hidden from specific contacts. This is a SMS client, not a chat client, and revealing a user's online status is highly problematic both socially and security-wise. I can't help but wonder how many lives this feature has ruined.<p>(I am talking specifically about the "online" indication, not the "last seen" information, which is also invasive but can be turned off).
