I can think only of deception on purpose. Like, they have a million users without any attention span so distros need something that sells itself as a streamlined package without deviations for UX with pro helpdesk support, so that DEs or whatever else with volunteers in development and support can work without being suffocated by triaging absurd bugs and suggestion of new features never backed by a pull request (and even then, a good FLOSS project should add them to the test harness, change docs, etc). So maybe GNOME/systemd out-of-the-box wouldn't make the luser scream for malfunction at first sight. I don't know.
