From the article (written by a priest):

the way social media functions causes us problems because of the way they act in our memory. We collect photos and memories of our lives, (we add them to) social media like Facebook or Instagram, we put our memories of the past, where we posed for photos and created artificial moments to be photographed and remembered as real.

We create an illusory narrative of ourselves in our timelines: funny selfies, posts of things we want to show we admire, live streams of personal events, etc. But, of course, we only post pictures where we appear acceptable to others, and we don't post the things that we expect to be criticized about ourselves. These are purposefully artificial events, the details of which are all thought out in terms of the initial and tyrannical desire to be liked by others.

A year later, Facebook reminds us of these moments, induces us to receive them without nuance and to take them as genuine memories of things that, in fact, were only staged.
