To me that's a weaker point of page. I'd rather read about why Facebook couldn't design a REST API that meets their needs, not why some sampling of "typical" REST APIs in the wild doesn't have the characteristics they want. Sure, they might not, but can FB build a REST API that does have the characteristics they want? The answer could still be no, of course.
