Kicksecure is security-focused operating system.
Whonix is an anonymous operating system and based on, hardened by Kicksecure.
In result, Whonix and Kicksecure have the same security features.
Any existing or upcoming security related features are always implemented in Kicksecure and then Whonix will benefit from these too.
That seems messy. I wouldn’t want to develop an implementation where users have to resort to such hacks.
Whonix for anonymity.
Kicksecure for security-only.
