E.g. I know that germans are very concerned about privacy, yet americans not that much. Americans are very concerned about censoring the bad people, other cultures (scandinavians?) aren't that much. - @andrestaltz
If you're going to bring nationalism into this, which I don't think is necessary, I wouldn't generalize so much. As an American I am very concerned about privacy and security, and that's why i'm arguing that you can't have private group messaging without cryptography.
While it's true that most Americans will take the "I have nothing to hide" argument when asked about whether they appreciate privacy, we also have to understand that many of the people living in my country and powerless to stop the terrible things that Silicon Valley and our government is doing.
This doesn't mean we, as a culture, do not value privacy and freedom of speech. In fact, both are written into our constitution.
Anyway, if we're going to generalize about nations, let's not generalize too much. There are many perspectives over here, not just the terrible perspective represented by Silicon Valley.
