" If APIs are copyrightable, the entire software industry comes crashing down overnight"
"Copyrightable" is a word used only by people who don't understand copyright, so I'll go nice and slow.
A copyright holder has have something that adds up to a substantial original work before they can try and to use it to make a claim of infringement. I expect the Supreme Court will simply affirm this. APIs were never not "copyrightable". All it means you need a license if you're going to copy a lot of that original work. So go get a license.
The internal emails at Google show that Rubin understood this very well - he had copied Java, and even used over 30,000 lines of Sun code. The Android execs said: we really should get a license. But with Sun being hippies, they decided to wing it. Not a problem unless a Larry takes over from the hippies.
Given your limited understanding of copyright, I hope to God you're not in the industry.
