Fair enough, although I think they _could_ focus on fundamentals and try to be better than Linux on the merits, which could pair well with a thoughtful desktop environment and strong software ecosystem. They of course won’t do this.

The previous approach I thought was more technically interesting - take advantage of Windows NT’s design to support multiple “personalities” - providing Linux compatibility without an extra kernel.

macOS proves it is possible to have a decent developer experience without literally being Linux.
