From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I haven't seen that paper before. The ones I remember were blogposts or web pages. In fact, this may be what I was remembering: https://www.gnu.org/software/hurd/faq.html Particularly the part about what happened with the port to different microkernels.
IIRC NeXT and OSX use Mach, but they don't use it as intended. I think they're mostly a BSD kernel with Mach functioning as an interface to userspace.
Hurd actually used Mach as a microkernel, and moved most functionality to userspace daemons. This meant that Mach's performance issues,, at least the ones related to IPC, affected the Hurd a lot more than OSX or NeXT.
And yeah, I think developer interest was the biggest thing that held it back.
