There is no "normal" way an individual can relate to these things(, or relate to the world at large). Social media is more a financially backed mind-altering alien invasion than some extension of human social life. And yet, people regularly shame each other or themselves about it. Or they provide prescriptive statements as if its about how many cups of water you should drink a day. Its all just a silly circle of normativity on top of a framework that just more or less sells and delivers ads.
Just kind of reflect on your impulse here to be mean to this person, or to poke holes in their story, show their hypocrisy. Why? Whats really at stake here? Is this really something like a moral failing? Do you counter them with a more normal way to be a person? It is precisely bad faith, in Sartre's schema, to act like you know, to forget the ineffable uncertainty of being human and to act like, actually, we are all users, and there are good ways to be one or not, or good places to be a user or not.
To find superiority at all in yourself for your particular consumption or social habits is, if you reflect honestly for a second, the truly shameful thing. We are all figuring it out.
