Lots of arcade games and other amusement machines made in the last twenty years run on desktop Linux.
Incredible Technologies games, Raw Thrills/Play Mechanix Big Buck Hunter Pro, Arachnid dartboards, and TouchTunes jukeboxes off the top of my head.
I was recommended by a well-known privacy guide to use Rethink with AhaDNS Blitz, but it seems to fail often; nothing resolves until the VPN is stopped and restarted. Any ideas or advice?
