They're not controlling anything by releasing open-source libraries/languages such as gRPC, Kubernetes and Go. Releasing these things don't give them control over anything that can negatively impact users; this is not Microsoft's embrace-and-extend.

Chrome, on the other hand, is worth worrying about. Unlike the other technologies you mention, it's a consumer application that legitimately lets Google apply Microsoft-style embrace-and-extend tactics, monopolizing the web and steering it in a direction that benefits Google more than anything (e.g. ads and tracking).

Kubernetes may have come out of Google, but it isn't even in their control anymore. If anything, Kubernetes is a strategic play to democratize cloud orchestration, undermining competitors such as AWS.

Good points. I don't see anything wrong with these individual open source releases. See my other comments about the larger trend this represents.

"Releasing these things don't give them control over anything that negatively impacts users" and "undermining competitors such as AWS" contradict with each other if you believe competition is good for users. The decision to release something as open source doesn't happen in a vacuum. Open source doesn't automatically make corporate activity morally good or neutral.
