Linux didn't get to where it is by throwing its weight around and dictating to others (at least, not much). Its success came from interoperability with everything, making it indispensable glue, and its adherence to standards was an integral part of that. As mainstream Linux becomes more insular and controlled by a single vendor, it becomes correspondingly less useful and less desirable. I don't want to be locked in to a RedHat world any more than I wanted to be tied to Solaris or HP-UX. I get occasional PRs for my software demanding that I add systemd-specific functionality, with the assumption that it's the only thing that matters, and people get annoyed when I refuse to compromise the portability of my already-standards-compliant software with Linux- and systemd-specific hacks.
