It’s not about converting people close to you. In some situations, you’re asking them to install an app just to talk to you, while everyone else they talk to is on WhatsApp. I personally have to use WhatsApp for work and for personal, otherwise I’d literally not get those messages. There’s no option when, if you stop a random person on the street, regardless of what OS their phone is running, and ask to look at their phone, it’s going to have WhatsApp installed. It’s like your phone having email; who the fuck doesn’t have email? It’s the same with Whatsapp, it’s just assumed you have it.
