I think there's certainly some blame that falls on the engineers at Facebook. But, in my experience, if you put any number of developers in a room, noone is going to come up with "let's help scam the elderly". That requires an MBA or two.

Nah, engineers like to solve problems. The silicon valley jerk ratio scene doesn't come out of nowhere. You can get engineers to work on solving just about any problem if you make it interesting enough to them.
