Actually its only the PS5 that's FreeBSD based. Switch runs a completely proprietary Nintendo OS that borrows a lot from Android.

[WhereIsTheTruth → rstat1]

A mix of the two

"partially Unix-like via certain components which are based on FreeBSD and Android"

[rstat1 → WhereIsTheTruth]

from the same article

"it is based on a proprietary microkernel"

"....Despite popular misconceptions to the contrary, Horizon (the Switch's OS) is not largely derived from FreeBSD code, nor from Android..."

It borrows very little from Android - I think it mostly draws some parts from stagefright.

Also borrows the whole of its compositor "nvnflinger" from Android's "SurfaceFlinger".

I'd call that a pretty significant piece.
