It's pretty clear at this point that if you still work for Facebook you don't care whether they do evil or not and, if you do, the money trumps your morals.
EDIT: you certainly can look down on people for whatever, i just don't think it's justified in this case.
in a similar vein, i wouldn't condemn someone who works at Exxon building analytics software, or engineering some rig valve, but i WOULD condemn someone who works there with the responsibility of absolving oil & gas from any responsibility for climate change.
is my position wrong? honestly im a bit unsure if it makes any sense.
