I've lived in Germany for years and I do feel like, if we're going to stereotype people by nationality, they're one of the most privacy-sensitive groups you'll find. This is the country where, by law, if somebody picks up a (land-line) phone in the house, any other phone currently in use has to shut off. I'm not saying you can definitely convince that friend to get off WA / FB, but it's worth a shot. (I don't know what to replace it with -- I mostly use Hangouts but it really feels like it's falling apart.)
