+** Remove proprietary repositories
+
+By default the Debian operating system includes references to a repository which can be used to install some proprietary software. Because the source code of proprietary software cannot be independently audited or patched it could contain malicious backdoors or malware, or more likely because it's unmaintainable it's just old and out of date and so contains security vulnerabilities which the Surveillance State can make use of via its [[https://en.wikipedia.org/wiki/FOXACID][automated exploit delivery system]]. It's a good idea to remove those repositories as follows:
+
+#+BEGIN_SRC: bash
+editor /etc/apt/sources.list
+#+END_SRC
+
+Then remove any references to *non-free*, save and exit. With that done you can be sure that all the software on your system is [[https://en.wikipedia.org/wiki/Free_and_open_source_software][FOSS]], and so can be checked, updated or customized as necessary.
 ** Enable backports
 
 To enable some newer packages add backports to the repositories.
