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.)
