Ubuntu founder Mark Shuttleworth says ACPI is a security risk. He says "arguing for ACPI on your next-generation device is arguing for a trojan horse of monumental proportions to be installed in your living room and in your data centre" and "firmware on your device is the NSA's best friend". He goes on to say, "Your biggest mistake is to assume that the NSA is the only institution abusing this position of trust – in fact, it's reasonable to assume that all firmware is a cesspool of insecurity, courtesy of incompetence of the highest degree from manufacturers, and competence of the highest degree from a very wide range of such agencies." He suggests open-source, declarative firmware (ACPI or non-ACPI) as a solution.
