Many have written about how being under constant surveillance changes
a person. When you know you're being watched, you censor yourself. You
become less open, less spontaneous. You look at what you write on your
computer and dwell on what you've said on the telephone, wonder how it
would sound taken out of context, from the perspective of a
hypothetical observer. You're more likely to conform. You suppress
your individuality. Even though I have worked in privacy for decades,
and already knew a lot about the NSA and what it does, the change was
palpable. That feeling hasn't faded. I am now more careful about what
I say and write. I am less trusting of communications technology. I am
less trusting of the computer industry.
