As someone else mentioned, the HURD was started before Linux existed back when micro-kernels was all the rage in academia.
Stallman said that by using the mach-kernel they hoped to get finished faster, as it turned out this was a big mistake which he acknowledged as his own and as soon as Linux took off they started focusing on improving the GNU toolchain in conjunction with Linux.
The Hurd is still in development today because there are people who like working on it during their spare-time, just like all the other alternative kernel/os projects out there.
