Final answer:
Ralph was fired because he was seen as responsible for the copyright infringement issue with the Magicword software, leading to financial losses for Amcott.
Step-by-step explanation:
Ralph was fired from Amcott because he was held responsible for the loss that stemmed from the copyright infringement suit related to Magicword, the software that converted French text files into English.
Despite his accurate sales forecasts, which projected annual sales of $7 million, the failure to recognize the copyright infringement issue which led to a halt in sales and a substantial financial loss for the company was deemed a significant managerial oversight. His claim of being a scapegoat suggests that he felt others were to blame for not properly investigating the legality of Magicword before its purchase.
