Darkness reigns over Wikipedia as official dark mode comes to pass
(arstechnica.com)
This is a most excellent place for technology news and articles.
It doesn't seem to work on the German Wikipedia. Super weird decision to tie display settings to a language.
It does not work with spanish either
Edit: moreover, if you configure it by accessing an english article and then switch languages, darkess mode goes off
IIRC the wikipedia for each language is pseudo independent. This feature will eventually make it to all, I hope.
