BP are lying scum who should be sued into bankruptcy. There's a surprising consensus around the point.
That's hardly accurate.
First of all, BP are no more lying scum than any other oil company. They've responded much more co-operatively than Exxon did after the Valdez spill, for example. I think that the organization as a whole recognizes that their only chance to survive as a corporate entity is to be seen to be doing the right thing in this situation. From the top level, the cheif executives have take this approach, however, there are many middle managers in the organization that have, for years, been trained to squeeze every cent out of every transaction and they are responding reflexively with this attitude despite the unusual circumstances. When inappropriate contract clauses or apparent nickel and dimeing on salaries is revealed, the root cause is usually some dim middle manager who followed the usual pattern without thinking.
However, it's still true that the oil industry in general has as its primary and most important goal to make as much money out of oil as possible; full stop. Any spin suggesting that they care about anything else is just PR and not part of their true motivation. Sure, it's necessary to pay lip service to the environment and pretend to care about safety to be successful in this business. But recent events (as well as many other past examples) show only too clearly that any pretence of responsible behaviour is only skin deep.
As for bankruptcy, don't hold your breath. The cost of cleaning this mess up, and BP will pay their bill in the end, will be a mere fraction of what they earn this year and won't even lead to a non-profitable quarter. The biggest loss to BP is that they can't sell the oil from that well and that's going to hurt their bottom line much more than the cost of cleaning up the mess. There will likely be lawsuits for years to come but that will merely ensure that there are no layoffs in BP's legal department and won't really impact the company in any significant way.
