Actually, no, not all major distributions have caved and adopted systemd: Other than Gentoo, there is also SlackWare. (There is also Devuan, which is "Debian without systemd", i.e. minimal changes to allow for systemd not to be used, but of course that doesn't change the default for everything depending directly on Debian.) There are all sorts of complaints against systemd, some may or may not be overblown - I certainly have not investigated many use cases - but the problem is with the core of it: A single software project gradually taking over more and more of the OS userland. That is simply not a good thing to stick on your system. No less importantly, I don't believe systemd solves any significant problems vis-a-vis its alternatives.
