Re: "Religion gave way to pragmatism"?
"Take Linux, for example. It's hard for me to advocate, as I used to, something that has now fully embraced the Windows mentality via systemd."
Contrary to popular belief, Linux does not have to use systemd. There are plenty of distributions out there who have not drunk the coolaid. Do be a nice chap and try not to spread FUD.
And then there are the BSDs, which I note you haven't even mentioned in your learned treatise ...
