Comparatively to the rest of the internet, it seems like there are a lot more Germans here. I’ve always assumed it was just because I was on a German instance and was in a sort of echo chamber (join feddit.org btw 🥳), but I just checked Fediverse Observer and it’s the 2nd largest country by users. Additionally, the German instances seem to be the biggest non-English ones.
It's from all their camps, workshops, Erfa's (Erfahrungsaustauschkreis) and especially the annual Chaos Communication Congress which is huge and attracts the scene worldwide.
The last congress was named 38C3: Illegal Instructions if you want to search on their media hub. A lot of the talks are in english.
