This is purely speculative. From my talks with sys admins, all the ones I've met greatly appreciate systemd. Also timers and cron have different requirements, notably timers can do much more. Also timers is purely optional and most distros DO use cron.

There's a major disconnect, I've seen, from what systemd haters proclaim and what is reality. Nobody is forcing anything, you don't have to use 99% of systemd, it's not a monolith, and many people do want the features. To be clear, this isn't my opinion - this is the truth. You can find all this out by perusing the repos and mailing list.
