Linus is an engineer/tech. He dislikes theory work because it often gives nothing in practice.
However, specs are not always theory, and they may be usefull, as well as docs. He may be smart enough (or know linux code enough) to not need any doc/spec, but it's not the case of many other people. Some specs are good, and sometimes necessary.
He cited OSI model, well, but I can assure you I won't go in an airplane if it was done with Linus' practices... There are specs in some places that are good, and that are read and followed. Even in non-dangerous domains such as Web standards, specs are necessary, and those who don't follow these specs make crap softwares/browsers!
Moreover, in Linux development model, which is fuzzy and distributed, not directed, defining the software may be vain. However, in a commercial environment, defining the spec is really writing a contract, which protects both the customer and the editor. Specs there defines what the software can and must do, and ensures it will do. Linus obviously lacks of experience in industrial and critical projects. He may be right for the kernel development (however I still doubt it should be so entire on that subject), but he's wrong on many other domains.
IOW, Linus does here a generalization which is at least as wrong as are the examples he cited. As we say : "all generalization are false".
If he finds a bad spec, either it throws it away, or he fixes it. It's the same for technical docs. But he shouldn't tell every specs are useless and bad. That's wrong.
