I think this is more of a case of Microsoft validating these ideas from open source (X11 dialogs are not exactly "Linux"), rather than "stealing" or "borrowing" them. Wow, extent-based filesystems not exactly the most resilient... the real question here is why Cutler and Co. "borrowed" ODS-11/Files-11 wholesale? In a larger sense, the article has a clickbait title, and I fell for it. If it had read "Microsoft validates a few open source software choices", hardly anyone would have bothered reading it, I guess.
