My only counter-argument, and it's not even a counter-argument really, is that this is a fact of life that exists with or without Facebook.
My personal pet peeve is that I don't want to own a mobile phone at all. Not even a dumb phone and not even a landline. If I find myself in an emergency without the ability to dial 911 that's a risk I'm willing to take on a personal level. I just don't want a phone because I find the idea of a noise making device that can interrupt me at unexpected times to be a crime against humanity. But more and more essential services like banking are assuming that people have smart phones. My bank would deny services to me if I didn't even have a landline, since they require a phone number tied to their account records. My work assumes that people not only have their own smart phone but are willing to install authenticator apps for MFA etc. And my workplace is not alone.
If it's not Facebook that "everyone" is using that leaves minority opinions wishing for an alternative, it's something else.
