All designs break at some point. There is no such thing as hurricane proof. In this case the sub-surface safety valves designed to prevent oil spillage, failed. To take another industry, there are design risks when it comes to seatbelts, brakes, crumple zones, tires, fuel lines, etc, etc. Better designs for each of these safety features already exist. You can't simply wave a magic wand and ban cars with older designs. We have been making progress on all fronts when it comes to safety. I have family who has worked on oil rigs, and what we have now is a hell of a lot better than the rickety explosion-prone rigs from 60-odd years ago.

>We're letting companies profit off of the environment without being responsible for cleaning up after themselves when shit goes sideways.

That is just a hyperbole and is not grounded in reality. Ironically, in this case, the company lost the oil, lost the 'money', wasn't able to profit, and went out of business. Looks like you got what you wanted. :)
