Presentation (in German) about OpenRailwayMap at GPN (Gulaschprogrammiernacht).
I would guess they are upset they engaged with a german language post when they set their account to show only their, presumably english, language.
I speak German just fine. It’s for other people. What’s the point of having a language setting if people are just going to stick “English” there?
Because this isnt German local news or something, this is a presentation on the inner workings of the railway map. Might very well be interesting to people regardless of language, you could probably turn off the audio and watch it with subtitles.
On principle you are correct though, the language setting isnt properly used most of the time.
