I should have said something else. I suspect the Pure OS has been specifically dovetailed to fit the Librem laptop. While the tech people at Librem/Pure are good natured and willing to help us a bit in installing Pure onto other hardware, they do not promise tech support, can not afford in time, to help for installing Pure to non-librem hardware.
I also suspect that it might be valid to say that the Librem/Pure OS is intended to stop things like Surveillance Capitalism, not to be a means to prevent power groups, like the NSA from being able to spy on us.
Sorry if OP feels I have spoken on things not germane to OP original Question. Might be our Moderator will want to offer some other explanation besides my suspicions of how things are…
