Curse of knowledge - I forgot that it's not obvious that I'm a security person! Should have mentioned that!

So yes it's popular... in the security community. In the Netherlands, it was also used, but usually reluctantly when the other party asks for it and it cannot politely be refused.

GnuPG is developed by Werner Koch that's German, there are a lot of German startups that work on PGP too (e.g. https://www.cotech.de).

I also used PGP to communicate with customers from Germany but it's not that every German customer of mine uses it.

As a German, so would I. Because thats news to me.
