How do you know the intention of a fork without their own explanation? It was unknown at the point of posting, and posting title is still technically valid.
This posting let you know their intention. Isn't it newsworthy?
"Google employees are contributing to another project" is not newsworthy, no. Neither is them creating a github fork unless you have evidence that they do not intend to use the fork for the main reason people create GitHub forks: contributing.
