It’s pretty difficult to explain to non-developers what was implemented by the Kicksecure / Whonix project and what wasn’t in simple terms. Easy to mistakenly underestimate or overestimate.
On Why Whonix ™ will always be Free as in Price as well as in Freedom we write:
We stand on the shoulders of giants - Whonix ™ and many other Libre software projects are only made possible because people invested in writing code that is kept accessible for the public benefit.
Countless freely available software packages such as Linux, GNU, Debian, Xfce, Tor and thousands more weren’t created by the Whonix project.
On Placing Trust in Whonix ™ we write:
In one sense, Whonix ™ is the simple union of Debian and Tor and a mechanism to glue them together.
So countless people deserve attribution.
