Not everyone makes use of those features and the last time I was using a Red-Hat system, it was for Java deployments, which is also not Linux related in any form.
Same applies to the C, C++, Fortran and now Chapel code that usually runs on HPC clusters.

Everyone uses systemd... I hope people are smart enough to not fall for it and not use all the scope-creeped features of it but if you add all the little things up, it turns out that we are getting more and more stuck with linux.
Except that things like systemd and a lot of redhat related software rely on Linux-specific functions like cgroups so they are not portable. Good luck replacing Linux even if something that much better comes up.
