Saying the Nintendo Switch is BSD based is a bit of a stretch, Horizon (the Nintendo Switch operating system) runs a proprietary, fully custom microkernel and has some utilities from both FreeBSD and Android.

> Despite popular misconceptions to the contrary, Horizon is not largely derived from FreeBSD code, nor from Android, although the software licence[14] and reverse engineering efforts[15][16] have revealed that Nintendo does use some code from both in some system services and drivers. For example, the networking stack in the Switch OS is derived at least in part from FreeBSD code.[15] Nintendo's use of FreeBSD networking code is legal as it is made available under the permissive BSD licence, and not even particularly unusual – for instance, the Microsoft Windows XP TCP/IP stack was originally derived from BSD code in a similar fashion.
