It only took a day for the death of three Tesla Motors employees to be converted into ill-advised advertising. Witness the email ad below, circulated to Silicon Valley venture capitalists near the scene of the plane crash.

In terms of exploiting tragedy, this isn't as bad as exploiting the 9/11 attacks by turning them into product endorsements. But it's close, thanks to this line: "Prudent risk management dictates that multiple executives should never travel together, be it on a private plane or commercially." Ah yes, blame the victims.
