As strongly as anyone can disagree with something, I disagree with the "undeserved" part of this.

It’s a little bit interesting to me that XBill has the eponymous figure replacing a diverse ecosystem of OSes, not just Linuxen, with his own. That probably is a sign of the times, when that diversity existed in fact and you might be playing that game on an HP-UX or another prediluvian machine. Maybe not though, maybe the waters were already rising. You might even imagine with some fairness an XTorvalds in which you vainly try to save the BSDs and proprietary Unixen from a Linux monoculture. It makes it easier for me to charitably accept how some systemd detractors describe themselves as for init diversity, even if non-systemd and non-sysvinit inits on Linux seem like a curiosity, rather than assuming that they are just contrarian. It is part of a tradition of valuing a variety of ideas and implementations of ideas, even when it becomes quixotic.

I did not find the XLennart very graceful neither.

I admit I am also biased about the original XBill one.
