Quality code, simple design, and/or security could differentiate.
If none of those applies, then the community should choose the alternative that does offer those things.
In my opinion, systemd does have some very good features in it's core function space, it just has some major implementation and kitchen-sink issues that need to be fixed.

I am well aware that the corporate incentive militates against doing what's best in the case of systemd.
There is nothing, however, that requires systemd be exclusively or even significantly driven by Red Hat, the community is completely free to fork and fix the project.
The Linux community (of which Red Hat is only a small part) has a responsibility to itself to reject or repair overly complex and insecure solutions to the needs of a modern operating system.
There are already projects underway in various places that begin to address these concerns, and the natural self-interest of the community will tend to bring those to the forefront, absent external interference.
Red Hat will, eventually, either recognize the constraint (do what's best for the community or the community will go elsewhere) or cease to exist; both outcomes are eminently reasonable and beneficial.
I have no desire to tell Red Hat how to run their business, and they shouldn't listen to me if I did.
The quoted paragraph is more of a recognition of a common technology blindspot that happens to manifest in Red Hat's organization (and applies to the systemd design issues) than a prescription for action.
Note, I don't pretend to have the time or skill to fix systemd either. I just made some observations that, if it's bad enough (and it might be), there could be enough interested entities who do have time and skill to fix the problem.
