It seems that a good number of Linux users who despise systemd as an init manager have a lot of time on their hands... From making websites bashing systemd, forking distributions over their position of using systemd, personal attacks against systemd developers, to writing page after page of forum comments about negative points of systemd. There's now even an anti-systemd game.

XLennart is the anti-systemd game that's a modification of the XBill game. The game is self-described as "a hacker named, 'Lennart' who has created the ultimate computer virus that is cleverly disguised as a popular init system. XLennart is commentary on a certain Linux/Unix topic, but I'll let you figure out which one."

In terms of the game-play for this anti-systemd game, "The little people running around the screen are trying to infect your computers with SystenD [TM], a virus cleverly designed to resemble a popular init system. Your objective is to click the mouse on them, ending the potential threat. If one of the people reaches a computer, it will attempt to replace your operating system with the virus it carries. It will then attempt to run off the screen with your vital software. The game ends when only 1 (or 0) of your computers are being productive. Additionally, some computers are connected with network cables. When one computer on a network becomes infected, a spark will be sent down the cable, and will infect the computer on the other end when it reaches there."

XLennart is open-source and available via GitHub.
