What you say works for me, but unfortunately it doesn't work for a lot of folks in countries which are hyper-dependent on certain apps like WhatsApp (Brasil, India etc). These places use WhatsApp for literally everything - like I heard about professers sharing lecture notes and assignments over WhatsApp, govt agencies accepting documents and applications only via WhatsApp, customer support for many companies is also done only via WhatsApp (with no option to call or email), many payments are done via WhatsApp, restaurants have reservations and booking confirmations done via WhatsApp and so on.

For these folks, WhatsApp isn't just some messaging/calling app, it's an entire platform. I consider myself lucky I don't live in one of those places, but I can imagine it would be really hard to live a modern life in such places without WhatsApp. And it's also scary and concerning how a single foreign megacorporation like Meta has a stranglehold over everyday lives in so many nations.
