I’m probably quite biased being German myself, but I feel like that things like privacy and security tend to be more important to Germans than to other folks. And I don’t speak just about the tech bubble, it shows everywhere.

To give a random example, when a license plate has been blurred in a photo posted anywhere, chances are high it’s been posted by a German. Despite the fact that there is no license plate lookup (like carfax for US, finnik.nl for Netherlands, car.info for Sweden etc) so a license plate wouldn’t even reveal anything to anyone, yet we treat it like a secret on instinct. If you ask such a German why he blurred it, he probably won’t have a reasonable response, he just does it because he feels like it.

Getting back to topic, this might not be the only explanation, but I’m pretty sure it’s a noticable factor why Germans are especially present on platforms like this, i.e. platforms that tend to respect the user’s privacy more than the big tech corporations.
