I’m not sure what that tells you in the best case though.. They could surely break out a line for Kernel, but then does the investment in Automotive Grade Linux count? Or Civil Infrastructure Project? Or whatever that new OpenSSF project is? If they spend $10M on hosting OSSNA, should that count? Does money spent supporting K8s somehow detract from the kernel work?
It’s just such a weird flawed premise of a measure I can’t imagine how it’d be useful in determining anything about their motivations.
