I disagree with you. A valid answer to the "What illegal activities" question is: None. Posters including you have overlooked that. I then went on to make the point that IF you go on to use those kinds of services to try and protect your privacy you should expect that your activities will be the subject of additional scrutiny. That was my point.
I also disagree with your statement that either people are entitled to privacy or they aren't. You simply can't be so black and white about it. People are sometimes entitled to privacy, meaning that nobody really gets to eat that cake.
And at this point in time, speaking out MIGHT be illegal. In Australia we actually have no right to free speech enshrined in our constitution. So yet again, nothing as black and white as the statement you made.
"Australia does not have explicit freedom of speech in any constitutional or statutory declaration of rights, with the exception of political speech which is protected from criminal prosecution at common law per Australian Capital Television Pty Ltd v Commonwealth. The Howard Government re-introduced sedition law, which criminalises some forms of expression." -wiki
