If you look into PlayStation from a software angle, it makes perfect sense. Sony has always been pretty pro-unix.
They had an official Linux kit for the PS2 (came with a custom Linux distro on a CD, a HDD, and a KB+M).
OtherOS was also a selling point on the PS3, and was only ditched when they realized it opened the door to major security risks.
Further, CellOS, the operating system for the PS3, and OrbisOS, which is the base operating system for the PS4 and PS5, are all based on FreeBSD.
So, a lot of their hardware is designed around Unix systems already. I know all their controllers since the Dualshock 3 are natively supported by the Linux kernel (no dongles or drivers needed in theory).
