According to Craig Venter, early detection is what we need to eliminate cancer:

The reason most people die from pancreatic cancer, for example, is because we almost always detect it in a late stage.

A counterpoint: Google believed they could attract better engineers (which can be explained either as genuinely more skilled people, who have more ability to choose where they work, or simply more passionate people) with the "Don't be evil" policy. Oracle existed all along. Google wanted to not be Oracle.

Now, Google has decided they want contracts like they're Oracle and they want staff like they're not Oracle. They can't have it both ways. It's not so much that Oracle is a more grown-up company because it learned to pursue profits and not good - it's just that it's easier to survive that way. (Hence the appearance that Oracle is a "normal" business; it's an easier way to run a business, is all, so more businesses do that.)

Nobody forced Google to be a public company. Nobody forced Google to grow as big as it did. Nobody forced Google to talk to China. They brought this on themselves, and they should have known that they couldn't do this and still remain Google.
