I’d like to add that it is not just about governments (democratic or otherwise). Large corporations wield disproportionate powers, in comparison with individuals, and may have a presence across countries and continents. Even if they don’t use the data directly, they may pass it to some other entity. I’m not comfortable with the idea that anything I read or write today may be made available one day to my current or future employer, customers, providers etc. ... In a way I have already internalized this idea. These days every time I use an electronic device I behave as if an unintended recipient was peeking above my shoulder. So my behavior isn’t as free is it was, say, in the 90s, before networked communication was so ubiquitous.
