This is What a a Tor Supporter Looks Like: Susan Landau
“Communications metadata is remarkably revelatory. Just knowing what number you communicated with, when, and for how long can reveal whether you are having a flare-up of MS, seeking an abortion, or thinking about growing marijuana plants commercially. All of this comes from the numbers you call, and not what you say. It's why keeping communications metadata private is so important.
“Tor protects such data. It's not just journalists who need such privacy. It's human rights workers (that's why the State Department supports Tor), law-enforcement investigators checking out questionable sites, the businessperson collecting data to make decisions, the worker checking AIDS information or Alcoholics Anonymous over lunch hour on her private device but using her company's ISP. In a world of increasing surveillance, there's increasing need for Tor.
“I first began using Tor regularly in 2012 when I taught a freshman seminar in privacy. For one assignment I asked my students to try Tor and write a customer review. Tor was very clunky then. The fact that you couldn't simultaneously use Tor and the Firefox browser seriously diminished usability for me.
“Tor has much improved. The program runs faster, it is more secure, and there's greater functionality, including the ability to simultaneously use Tor and Firefox. I am delighted, but more is needed. We live in a world of pervasive surveillance, and Tor provides an essential service. Give generously and give often so that we can protect a modicum of private space in our increasingly public world. The privacy you protect may be your own.”
