as i undestood pure os is debian based, pure os is with free software only, and main debian repository (and main installation) too
ofcourse there is other differences, but i’m not a pro, so i’m just trying the distros and try to understand, so i gonna ask you what are the main differences for a purist and for a normal user

thanks

Other than what you already noticed, we have PureBrowser and Tor installed by default, few other programs and default configuration adjusted for increased security and privacy.
