I think CNCF, or more generally, Linux Foundation projects are better characterized as public goods. Basically a bunch of companies, many whom are competitors with each other, get together to improve the commodified base upon which they depend. Saves a lot of $$$ that would otherwise be wasted in wheel reinvention or spent on license fees.

For the particular case of AWS now offering Kubernetes, is that:

- A win for AWS, since they can leech code without contributing back

or

- A win for Kubernetes contributors and users vs AWS, since now customers have the option of moving their Kubernetes workloads from AWS to other providers.
