C on Unix-like systems isn't so surprising. The K&R book devotes a large section to the Unix system interface for example, the Linux kernel is one of the biggest C projects in the world, and even when using a higher level language to write your programs you're ultimately calling into libc or wrapping other C libraries or syscalls. It's a case of "When in Rome, do as the Romans do".
