Which is why Steam would never do that. All they're doing is hosting a few gigabytes of files on their CDN. Why would they ever voluntarily remove a game unless it had broken some kind of law? Even games that were removed from Steam like Hatred could still be downloaded by people who had already bought it. I think you overestimate how much people are interested in their old games. People just want to move on to the latest and greatest hit.
