Fortunately K8s is _not_ a Google owned project. It's managed by the CNCF which spans many different companies. Yes, there are a lot of Google people involved, but it really is a community project. Maybe I'm being naive but that's how I see it at least.
According to Wikipedia, though, "Founding members include Google, CoreOS, Mesosphere, Red Hat, Twitter, Huawei, Intel, Cisco, IBM, Docker, Univa, and VMware." [1]
Ah yes. I just love that free community spirit. Top 10-15 contributors are all paid money to work on this by Google, RedHat, Microsoft, VMWare, Goldman Sachs (and I couldn't bother to check others).
That is, 18 billion net income last quarter, 15 billion net income last quarter, 141 million net income last quarter, 6 billion last quarter...
These ginormous corps solve their own problems under the guise of open source, and gullible developers fall for the community promise.
