Maybe you want to read the article again. I think that is the part where Mark Shuttleworth calls for an end to ACPI (italics in original):
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. I’ve been to Troy, there is not much left.
On the topic, I think Mark Shuttleworth is completely right. I would go even further and say that UEFI (a horribly complex specification, whose implementations clock in at dozens of MB of code) should be placed right next to ACPI on the list of things to be abolished.
