Yes, there are. You just have to live in one of the many many countries in the world where the overwhelming majority of the population uses whatsapp as their communication app. Like my country. Where not only friends and family, but also businesses and government entities use WhatsApp as their messaging app. I have at least a couple hundred reasons to use WhatsApp, including all my friends, all my family members, and all my clients at work. Do I like it? Not really. Do I have a choice? No. Just like I don’t have a choice on not using gmail, because that’s the email provider that the company I work for decided to go with.
Lots of people. I need it because it’s how my clients at work prefer to communicate with me, also how all my family members and friends communicate.
