Of course there should be a cleanup effort ongoing. But if new stuff continues to spill out every day afterward, there will be more to cleanup the next day, and the next, and the next, forever, until we reach the point where the leak is totally stopped and/or contained the source. It's weird/naive to criticize a cleanup effort that's been going on for months if the leak has also been leaking unstopped for those same number of months as well. It can never be totally cleaned up or restored until, at a bare minimum, the leak is stopped.
