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 don't think it's just Linux. I've been told MacOS also works very well on ARM. Maybe it's just Microsoft doing a bad job.
Mac OS was running on RISC processors back in the 90s, and Steve Jobs used them in his NeXT computers which used a variation of BSD, which was the basis for OS X which could run on PowerPC.
Apple’s had a ton of experience with RISC so it makes sense they’d do it well.
It’s mainly due to PA Semi acquisition. These guys were the ones responsible of making excellent PowerPC processors, which were similar to what ARM has now.
These guys are probably happier now that they have more resources, target devices and tightly coupled software.
