Personally, I get exasperated when people don't take the time to educate themselves before making broad and incorrect assertions. There is a huge amount of documentation, discussion and other sources of information about systemd available online. Moreover, there is the source-code, and even the packages in Arch one can try out. There really is no excuse.
Well for me I do not have the time to go about learning the latest and greatest init system, desktop environment, whatever. I still use KDE3, I use old school init systems... why? because I use my system to do work not to tinker. I need it to "just work" and continue working in the same way it has. I don't want to become educated on the latest coolest thing, I just want something that will work and work well. I do not have time to pour through documentation of systemd just to figure out how to work it. When change is just for change I do not like it. Calvin
