I am careful in how I use the Internet.
I generally do not connect to web sites from my own machine, aside from a few sites I have some special relationship with. I fetch web pages from other sites by sending mail to a program (see
git://git.gnu.org/womb/hacks.git) that fetches them, much like wget, and then mails them back to me. Then I look at them using a web browser, unless it is easy to see the text in the HTML page directly. I usually try lynx first, then a graphical browser if the page needs it (but I make sure I have no net connection, so that it won't fetch anything else).
I also browse from other people's computers, with their permission. Since I don't identify myself to the sites I visit, this browsing can't be connected with me.
One consequence of this method is that most of the survellance methods used on the Internet can't see me.
Another consequence is that I never pay for anything on the Web. Anything on the net that requires payment, I don't do. (I made an exception for the fees for the stallman.org domain, since that is connected with me anyway.)
I would not mind paying for a copy of an e-book or music recording on the Internet if I could do so anonymously, and it were ethical in other ways (no DRM or EULA). But that option almost never exists. I keep looking for ways to make it happen.
