Please if you are trying to use freebsd TRY jails (to shorten tldr, use iocage). They are just great :)
And dont go desktop. Just isnt worth it. Not enough people troubling with gfx support. Keep it as it is. Server.
There’s FreeBSD in almost every data centre. But it’s at a level most application developers just never see. Many infrastructure elements - from storage heads, to core routers, to enterprise application and security appliances - have chosen FreeBSD as the high quality, reliable, consistent, and liberally licensed base for their control plane software.
The point being, this is where FreeBSD has the greatest influence and adoption: as a platform, not the product, and not at all obvious even to those that thereby rely upon it.
That being said, yes it works great as the instance OS in EC2 and as a die-hard acolyte since 2.1-RELEASE you’ll pry my production application jails from my cold dead hands
Nintendo do use some code from the FreeBSD kernel in the network / sockets stack though - https://switchbrew.org/wiki/Sockets_services
And since FreeBSD is not GPL-licensed, it has exactly zero relevance as it means that no "lambda person" can use it, write code against it, etc... without paying the 2500$ of a devkit.
Sony could write their proprietary drivers for any OS - just look at nvidia which uses the same driver with just a microscopic shim across linux and windows.
