FUCK YOU OPEN SOURCE FREAKS clause to any contributions.
And after you sign this idiotic anti open source agreement you are allowed to contribute to an inferior init system soon to be capable to do session management for the sole purpose of vendor lockin. 'Yes thats right; We will end with a bunch of apps developed for "Ubuntu Linux" not Linux. and they will use upstart session. Pretty smart tactics by Canonical to do away with "the competition". There is a major risk of a damaging fragmentation coming to the linux desktop and people think it is funny because they can mock some systemd developers who work in the open without skunkwork agendas.
Anyone who will accept a deal going: "Give us your copyright and we will grant you a less capable init and session system guaranteed to create further fragmentation" is a bunch of neckbeards. This is gonna be years of "fun" if people really accept Canonicals crap.
