Are you accusing Google of "large part copied code" based on an old commit which is not even used in this official launch? Do you have any evidence from their recent commit? At least I don't see the current two repos are anywhere alike, except for that you both implement the same interface. Also, they did reach out to you and you just didn't respond, so why are you complaining now?

It makes me sad that no one here cares about whether your blame is true. And I'd expect you can provide more convincing evidence. But looks like the accusation is not even true. It's not fair for those contributors man, I hope you can apologize.
