Why have you chosen to mingle the verbatim copying of function implementations (range check) with the API definition copying? You say google "admitted it" which is a loaded term and you use that to say "This isn't a cleanroom implementation". Google conceded the direct copying of one function implementation and thought it not relevant - IIRC the jury awarded Oracle $1 for that. The rest of the function implementation ARE clean room implementation, and the API definitions are claimed by most of the industry to not be copyrightable.
If this holds up, every programming language that was not originally produced under a suitable open source license will need to be dropped because all software written in those languages will be infringing an API copyright.
