Dear Facebook employee,
The moral runway you thought you had when you began working at Facebook to impose the will of Mark Zuckerberg on this planet was always shorter than you might have thought. It has long since run out.
If you can leave and survive, you have a moral obligation to do just that. If you can sabotage something on the way out, you have a moral obligation to do that, too.
The machine that you built for Zuckerberg to control is one that feeds on our species' misery like a parasite. Think of the world your children will inherit.
Quit. Abandon Facebook. Save Earth.
A human from Earth
