I've got several infosec friends at Facebook right now, all new hires, trying to preserve our democracy from attacks. I don't consider them morally bankrupt at all.
Minimizing the damage of collecting that information is maybe not directly evil, but helping kick the can down the road to the point where facebook is so deeply networked in our society its unremoveable doesnt seem like a high horse to be riding on.
Or, have the former earned a monopoly on the latter/our-species?
And unfortunately Hillary Clinton did it to Putin first, probably using similar methods.
Hahaha, thanks, that was a good one.
