And that Linux users who hate DRM will eventually run dual-boot.
Not hiring developers is dependent on "penguinophobia" or whatever you called it, not really on fear of the market size. I.e. as you said, it's not about money, it's about management being strangers. For instance Flying Wild Hog explicitly hired Linux developers to work on their engine in-house. And multiple other studios did, as I already said before. CDPR could do it, even while being picky about who they hire.
