You should be glad to give freedom to someone by giving them a GNU/Linux PC.
Trisquel: https://trisquel.info/ is an excellent choice as it's easy to use, note that some hardware will refuse to work (although that's usually only really 802.11ac Wi-Fi cards and decent external or internal 802.11n ones are rather cheap).
I found Trisquel works fine with even a card as new as the gtx 970 thanks to Nouveau, although the card is stuck at idle clocks as the fans refuse to spin without proprietary software that is cryptographically signed to prevent its replacement.
Even newer AMD ones should work with a native resolution, but you won't get 3D acceleration nor suspend.
