The thing is, as someone stated below, Oracle is all about short-term wins. If Oracle wins this patent suit against Google and gets lots and lots of damages from it, that's nice, but it'll scare everyone away from Java. That's not good for Oracle or anyone else. If they'd just cool their jets and let things like this slide while focusing on creating great Java-based products and improving the Java ecosystem, they'd have much better long-term prospects. Even Ellison stated that Java is the most important product Oracle has ever acquired, and he's going to kill it in desperation to milk every last cent of licenses that he can get today.

If Oracle continues with this kind of ruthlessness, they may squeeze several million out of Google et al, but Java is done for. Nobody will want to use that platform anymore because it will be too risky legally. It'd be a huge opening for .NET and other competitors. Java would go the way of COBOL, only running in the darkest abysses of megacorporations that never modernize.

You can be happy that Ellison doesn't play this "good for developers" thing, but what's good for the goose is good for the gander. By promoting software development and Java development specifically, Oracle would be ensuring generations of Java programmers, and lots of Java-related services and licenses from enterprises. If someone without any programming experience learns Java to write code for Dalvik/Android, as they may because Android is a "cool" platform that would attract young programmers, they can and likely will go on to big corporate environments and continue to work in Java.
