I see that this could go bad for Valve, but the principled side of me thinks this sets a bad precedent for Value and the gaming community at large to be asking for permission from publishers/developers to green light a tool that helps people play games that are no longer able to be played. (if I am understanding this correctly) Retro games are in jeopardy of being lost forever because publishers/developers actively work against making it possible to preserve game history. If that doesn't do harm to the common good, I don't know what does.
