Germans may be more likely than Americans to think of "privacy" as something they want to be protected, but that doesn't at all translate to a cultural understanding of data protection. We don't want to be "spied on" but that only translates into an expectation of legislature, not into much real activism.
There was a short-lived popular support of the Pirate Party around free culture, privacy and transparency but as someone involved at the time I have to confess for most people this was mostly fueled by fears of losing the ability to listen to music and watch videos prior to the rise of Netflix and music streaming services.
There's an old cultural cliché of Germany being personified by a tired man with a nightcap as a joke about Germans being politically unmotivated but regardless of why that continues to be the case, it still very much describes how it feels if you try to motivate Germans about any issue beyond a few performative protests.
Maybe it is the way it is because Germans like it that way, not everyone needs to have photo of their house. Not necessarily hating the internet.
Also, I hated the fact that Germany did not have Street View, used it extensively at other places to pick neighbourhoods to go or not to go.
When I asked people I met how comes you don’t have Street View here, they all said that they liked their privacy and it has to do with the times when the government was watching everyone, so they are more cautious about it.
