German courts think the internet revolves around German laws. There are some really insane cases, sometimes they will consider a website to fall under German jurisdiction simply for having a German-language version (somehow ignoring that Austria and Switzerland exist, ignoring German-speaking minorities in other countries, ignoring that a fully automated translation in 100+ languages is now possible at the click of a button).
