Good question and good answer!
The current level of general surveillance in society is incompatible with human rights. To recover our freedom and restore democracy, we must reduce surveillance to the point where it is possible for whistleblowers of all kinds to talk with journalists without being spotted. To do this reliably, we must reduce the surveillance capacity of the systems we use.
Using free/libre software, as I’ve advocated for 30 years, is the first step in taking control of our digital lives. We can’t trust non-free software; the NSA uses and even creates security weaknesses in non-free software so as to invade our own computers and routers. Free software gives us control of our own computers, but that won’t protect our privacy once we set foot on the internet.
