Re: This article conflates two important issues
"If Google wins I can pinch 11,000 lines of someone else's copyrighted OSS code and disregard the license terms entirely. And if 11,000, why not 12,000. And if it's widely distributed already, why not the whole lot?"
If Google wins you can use an API of any length. That doesn't mean you can use the code that implements the API and disregard the license terms.
If Google lose it means you can't code against some library without having permission from the copyright holder(s) of that library. What's that you say? I already have a licence for the library so I have a licence for the APL? Not necessarily. You might be a third party developer; your customer has the licence, you don't - now how do you do your job?
Be careful what you wish for - you might just get it.
