NTFS was designed back in the mid 90s, when the plan was to have the single NT kernel with different subsystems on top of it, some of those layers (i.e. POSIX) needed case sensitivity while others (Win32 and OS/2) didn’t.
It only looks odd because the sole remaining subsystem in use (Win32) barely makes use of any of the kernel features, like they’re only just now enabling long file paths.
That comment was from a few years ago and wasn’t in relation to Linux, and the company he co-founded made some pretty useful things (And revealed the Sony rootkit in 2005) before MS bought them.
