Its an exaggerated non-issue
Linux is not a uniform userbase. Many systems will be affected by this. Many users will be fine because they use a well used and maintained distro. Many servers and embedded systems will not be fine.
That raspi running your pihole that is never updated? Yeah that might just stop booting next time there is a poweroutage and you wouldn’t know what’s up.
German here: in german all nouns have a gender. and virtually all nouns used to describe people in general are male (like user, human, citizen) and a majority of professions as well. As such using male pronouns in documentation is common as you refer to a user (and the word user has male gender). However there is a big debate in Germany about gender inclusive language that moves away from this “generic masculinity” of nouns. And of course the political left is pro inclusivity while the right is against it.
So if a (german) dev is actively defending the use of male-only pronouns they probably fall into the anti-invlusive-language camp in Germany as well. Its reasonable they would make the mistake when just translating from German, but starting a fight over changing it is sus.
