I want to push back on this narrative - I got off facebook and now my friends just text me instead. A few of my friends also got off facebook. Sometimes I can't see a facebook event so I text a friend asking for details. It's fine.
In some countries it has become difficult to live without a WhatsApp account. I'm doing it, but it's a pain since WhatsApp is used for everything that phone calls were once used for: schedule appointments, keep in contact with your kids' teachers, buy and sell goods, etc. The same numbers often won't pick up the call, or it will be simply turned off (since it's used just for WhatsApp).
Imagine living without a phone, or whatever is equally important in your area. Sure, it is possible, if you're at the right level of masochism.
Of the people who accumulated in my Facebook friends list over the years, the only ones I know who actively use Facebook still are almost entirely using it to have stupid political arguments with each other. It really has snowballed and bred derangement.
Facebook isn't the worst of it. WhatsApp is, in those areas where it is the de facto standard app for texting. This is not the case for Americans so they are mostly blissfully unaware of it, but just imagine literally not being able to text anyone.
I dumped Meta probably a decade ago, and anyone who wants to get in touch with me does so through e-mail.
But I still have two relatives stuck on FB Messenger. Even if I contact them via SMS, they still respond to my dormant account in FB Messenger, because Messenger is where all of their friends are. To them, it's the only messaging app, and have no idea why it doesn't work sending messages to me.
