The old conflict between Linux and Microsoft was never only technical. It also represented control, licensing models, work culture and dependencies.
Today the situation is more practical. Linux runs in clouds, data centers, containers and automation. Microsoft is also a platform vendor, developer tooling provider, cloud operator and part of many open-source workflows.
For XvX, the important question is not tribal alignment but operational fitness: open interfaces, traceable deployments, maintainability and systems that avoid unnecessary dependency.
