"FreeBSD works perfectly on Graviton" doesn't seem like it would move Amazon's quarterly financials. Does Amazon have any real history of sponsoring open source coding, when it is not a "d'oh, obviously this'll make Jeff richer and/or more famous" decision?
They have a history of working with open source projects only to the extent that allows them to push some of their work upstream so that the burden of maintaining it is shared, while retaining the rest of it as proprietary solutions that give them advantage over competing businesses.
Amazon has made substantive contributions to OpenTelemetry. Which, I suppose increases consumption of AWS in a roundabout way by ensuring people will not have a crashy, buggy mess when scaling up microservices, but doesn't directly drive CloudWatch consumption (because CW is not a differentiating, big-revenue-driving product, and OTel doesn't lock you in)
