You really don't understand that the power play comment? Don't be deliberately naive and address the comment directly. He's referring to the way systemd has used it's foot hold as an init system, to then leverage into adjacent software, such as udev and system logging. This is not just creating an integrated system, that would involve just using well defined interfaces. This is a power play to reimplement them "his" way. What is a distro to do now. Take on the new "features" or revert from systemd?
