I don't think that's Google's job at all, especially for a competitor's product.
Their project is to identify security vulnerabilities and disclose them to the public, in the name of public interest. We always have to assume worst case for security vulnerabilities, it's kind of the whole job of being a security researcher to determine what could have happened. Their job isn't to make Apple's users feel better.
It's also not Google's fault that media known for being wildly off-base when reporting on technical news was predictably off-base again.
