I wonder why the BSDs haven't caught on for embedded appliances and phones while Linux did with a more restrictive and less business friendly license. Sure some companies like iXSystems and Juniper adopted BSDs, but the vast majority used Linux.
Both the PS4 and the Nintendo Switch run on FreeBSD, by the way.
Not exactly from what I've read, the PS4 runs 'Orbis OS' which is based upon FreeBSD 9, meanwhile the Nintendo Switch is using the network stack from FreeBSD, but also stuff from Android and the custom OS they wrote for 3DS.
