Nobody believes that a free toilet will be magically cleaned up and maintained, somebody has to do it, and that person would better get paid for it. Sharing a toilet means that you flush, clean up after yourself, and always leave some paper, it’s basic manners. And yet, like toilets, as FOSS gets used by more and more people, it gets more likely that you will see obnoxious people that shit all over your commons and then complain about it. And nobody will want to take care of it.
Treating correctly the people who work on the software you use is just basic FOSS hygiene.
Wenn Du an einem Gemeinschaftsprojekt oder Free-Open-Source-Software arbeitest, dann arbeite sauber und hinterlasse keinen Dreck.
