This is going to sound like whataboutism, but while I deleted my FB 10 years ago, it is worth noting that there are also legacy factors like CNN & Fox News (>200k dead in Iraq,) the petroleum cartels, proudly neo-nazi friendly X.com, the greed is good C-suite circle jerk, and many more a-holes in addition to FB.
FB deserves derision, but it is far from the sole reason that civilization is declining.
