I thought most Steam games relied on remote activation/verification? Can you install and run them on a non-networked machine? If not, your LTO tapes are close to worthless because Valve (or its buyer) can still pull the same trick that Sony did here, with the same effect.

I'm not positive whether this is what they're referring to, but you can add external games to your Steam library. This is how the Steam Deck is able to run arbitrary games without needing to be in desktop mode, and the most straightforward way to run Windows games via Proton on Linux even if you obtained them elsewhere.
