Earlier quoted context omitted.
If a plane crashed, and the company that manufactured the plane was fined because they had an engineering bug, no one would blink an eye.
The analogy doesn't work. Barring malicious intent or negligence leading to death I cannot imagine (or remember) a situation where the company would be fined for a software bug.
Right. Companies like FB are entrusted with the private information of hundreds of millions of people. There should be investigations as there would be in a plane crash. If negligence is found, there should be appropriate punishment doled out.
