Nobody needs a margarita or any other addictive substance to function in society (barring actual substances issues). So it’s a false equivalence to compare apps like this.
An example in my middle aged life is that my kids extra-curriculars are all organized on WhatsApp. If I choose not to have a Meta account then my kids suffer when I am out of the loop on their events. Then of course all of the invites and venues are on Facebook. And all the parents post their pics to IG.
Because these apps are purposely designed to addict you, it is a real sticky thing to have to dip your toes in without getting sucked into a scrolling nightmare.
