Data privacy is a much more complex topic than we give it credit for being.
How easy is it for a stranger to find someone like you?
How easy is it for a company to find you?
How easy is it for the government to find you?
How easy is it to find ... yourself?
Somehow we have a system where the companies have it easiest, strangers (with a little $) are second... the government does OK and you? you know the least of all.
By knowing as little as possible it *feels* safer... more private, right?
