No thanks. Free software is based on irrevocable legally-granted rights, not some horrible company's largesses. If OpenJDK really is free software, I should be able to hack it such that it no longer conforms, stick it in a phone, and ship millions of copies without being sued.
Google's case isn't unusual at all. The same logic applies to anyone reimplementing an existing API with anything but bug-for-bug compatibility. Your view means that we can improve nothing, delete nothing, and deprecate nothing, since as soon as an API implementation diverges from the original, it's suddenly not for "interoperability", but rather an illegal appropriation of somebody's revenue stream? That argument is blatantly inconsistent with free software principles.
I'm going to give you the benefit of the doubt and assume that you're just an ardent Oracle fan, not a paid shill. It's really hard to tell the difference sometimes. Please reconsider the effect Oracle's litigation has on the entire software ecosystem. Consider that we wouldn't even have Unix if its view prevailed. You should be ashamed of yourself.
