My own hypothesis is that this is another instance of people being horrible at nuance.

I.e. "Everything and everyone is all good or all bad."

JK Rowling has donated to a lot of great charities and brought joy to millions of children, AND she's said nasty things about trans people. George Washington fathered a nation that the entire world is probably better off for, AND he struggled with believing in liberty while also enslaving people. Jeff recycles, but not as much as he could.

People are more complicated than just good or evil. It's probably good we couple some morality to art. I just wish our conversation about it wasn't so stupid and childlike.
