Interesting story. I'm skeptical that it's true, but if that's how things really went down, would the owner of the cabinet even have any kind of legal case? I mean, the tech was brought in to service other hardware, so there's no trespassing. They didn't steal or damage the cabinet or any physical component of it. And the owner of the cabinet doesn't own the IP or source code, despite whatever delusions wealthy collectors of one (or three)-of-a-kind games may have. The scenario would definitely be a betrayal of trust, but I'm struggling to come up with anything the owner could sue the tech over or charge him with.
