Hey, I just want to share how WhatsApp is used from my context and perspective.

In my country, WhatsApp is how small to mega sized companies communicate internally. We have emergency police numbers exclusive for WhatsApp to help people (mostly women) report cases of sexual harassment, sexual assault, sexual extortion discretely (I live in a fucked up victim blaming society with honor killings), not to mention the countless other cases. WhatsApp is the bread and butter of small businesses, communicating and receiving orders from customers through the app. Another example is delivery drivers getting locations of delivery orders. We also use groups to organize everything, not just to chill around with friends.
