Seem to be missing the "fair use" part of it all
Your entire argument for Oracle's ultimate success is that Google copied code. Which then leads to a fundamental misunderstanding of copyright. Copyright isn't just a "that's mine, you can't use it" tool. It has exceptions, it has nuance. And in this case, that nuance is fair use. That's what the courts are now deciding. There's a reason for what they did. There's a reason why it absolutely is necessary that Google wins this case, and it won't weaken copyright when they do, it'll ensure interoperability of systems continues without issue - FOSS or not.
Saying "Google stole code" is, quite frankly, irrelevant now.
