I am a native German speaker and developer. Literally every resource I look up on the internet concerning my work I look up in English. I actually start thinking about my problems in English.

When MDN shows me content in German the first thing I do is switch to English to lower the cognitive load.

I can just speak for myself, but jumping back and forth between two languages is adding unnecessary cognitive load.

I also never ever heard someone talk about the "Meisterzweig" in a Git repository.
