Sony DRM rootkit code (#8)

BNA's Internet Law News (ILN) - 11/2/2005 (today) linked to an article on CNET news titled "Sony CD protection sparks security concerns". Given their reputation, I would have expected a more critical analysis of the original article by Mark Russinovich. This article essentially said that the Sony DRM root kit code posed no real danger to systems, nor did it cost anything besides a little memory (cheap these days). This ignores Mark's points about system call hooking vulnerabilities and the overhead of scanning the executables of all the executing processes every two seconds. It also failed to mention that all files, regardless of source, starting with $SYS$ are hidden by the code.
