Last month when Facebook shut down, it came back but was missing a few things for a short time.
Facebook has had five different buttons for a while. When it left and came back online, it only had three at first (as seen in my screen capture above). No "Love" or "Care" buttons. Both of which use heart imagery.
Only the "Like," "Haha" and "Angry" buttons were there. The only buttons an online troll needs.
Facebook, like most corporations, had to sacrifice it's heart(s) to survive.
I assume it's running on artificial hearts now.
Maybe it always did.
