"That we are aware of, no pinball machine ever manufactured has been truly “safe” or “suitable” for a home environment"
Interesting statement. My guess is that the safety issue they are talking about relates to the need to maintain/fix pins by lifting the playfield and working on exposed electrical components and mechs. Maybe they are going for a plug-and-play modular system where features and mechs all sit on top of the playfield. Want a new game, just swap out the modules on the top of the playfield.
