And the judge in that case famously stated: “I couldn’t have told you the first thing about Java before this problem. I have done, and still do, a significant amount of programming in other languages. I’ve written blocks of code like rangeCheck a hundred times before. I could do it, you could do it. The idea that someone would copy that when they could do it themselves just as fast, it was an accident. There’s no way you could say that was speeding them along to the marketplace. You’re one of the best lawyers in America, how could you even make that kind of argument?”

I don't think this can be used as a counter-argument.

Most SO contributions are dead-simple; often just being a link to the documentation or an extended example. I mean just have a look at it.

Finding a comparable SO entry that is similar to Google versus Oracle example, is in my opinion much much harder. I have been using SO in the last 10 years a lot for snippets, and most snippets are low quality. (Some are good though; SO still has use cases, even though it kind of aged out now.)
