The evidence is strong that FB departure ranks high amongst people who feel over-monetized. Who were they monetizing? the kids. What did the kids do? They left, because it stopped being cool. Where did they go? Tik-Tok, which I believe has defied attempts to make it visibly monetized. (could be wrong)
"Like and subscribe" appeals only to other wannabes
I think I can argue the left will leave more than the right, because the right both respect "comment is free but reward has merit" and "it is glorious to grow rich" where the left is a bit more addicted to humblebragging and displays of value without attaching value to the display!
