The sooner we all begin treating Ubuntu and Red Hat Enterprise Linux as separate Operating Systems the sooner we can all move on from the "single standard" and "Linux on Desktop" debates. As an application vendor I always find it amusing when customers ask if we support Linux. My response is no, we don't support Linux but we do support Ubuntu 18+ and RHEL 8. Linux distros are so wildly different these days, not just in software but in ideologies, that this distinction is important, and there's nothing wrong with that.
