The nintendo switch doesn't use FreeBSD[0]. They supposedly only use the FreeBSD network stack, which also happen to be used in a great deal of other devices (It's so popular that it was ported into a userland library, see libuinet[1]).

Sorry but that's a pretty pedantic takeaway. This is high quality academic research at the forefront of CS/Systems Research, not a fancy bubbly website mandating you stop using nginx right now and switch to sandstorm. A "real" system would conceivably converge to be as good as kernel stack, and there are already projects like https://github.com/pkelsey/libuinet and https://github.com/rumpkernel/netmap-rumptcpip where you can share kernel code.
