@sendpaws @phnt lots, it's just never talked about publicly. A few off the top of my head for BSD:

Cisco
Juniper
Dell/EMC
Netapp
Netflix
Limelight
Nintendo

Illumos is something I am less familiar with. It probably lives on in some industrial controls type companies.

I wouldn't call Sony's usage "license dodging". They have taken FreeBSD and completely transformed it for their console's OrbOS. It still has jails which are used to launch games, they ripped out a bunch of syscalls from the kernel and added new ones, plumbed in changes to optimize it for gaming, etc. Even if they released the source it would be pretty much unusable by anyone else.

One thing people don't realize is that videogame consoles don't behave like a PC -- they don't have graphics drivers. That architecture actually makes the GPU usage slower / less efficient. Although my knowledge about this is aging and it's possible modern PCs have done things to close this gap...
