100% that even if that situation were to arrive, it would never go down that way anyway. It's a complete fantasy they have in their head about how they're not the corporate stooge they actually are along with everything else this guy views about himself.
Years ago MS decided to exploit IRC a very similar way by producing https://en.wikipedia.org/wiki/Microsoft_Comic_Chat - IRC networks and Channel operators hated this shit. It would add a tonne of extra encoding characters that weren't hidden in normal IRC clients.
All of this was because they wanted the critical mass of users and didn't want to work at establishing it themselves at the time.
(The funny part of it being that on the larger channels and networks, Comic chat was completely incapable of handling reasonably the large amount of chat volume in a channel)
Feels very similar where MS' entire philosophy is, if it works for us, we don't care if we spam non-MS people relentlessly.
Course it doesn't work that way, Sys-admins just end up banning/filtering or doing other work arounds to prune it.
Yeh, that's typical for the console homebrew exploits though.
(Or at least control of the resolver - the instructions looks like the author has a exploit server running for ease)
At the very least (beyond the extra TCP DNS fields) you need to ignore/drop the two UDP DNS requests the Wii U makes before failing to TCP.
I'd be interested to see a follow up in time to see what the IO wear-n-tear looks like.

"Using gokrazy instead of Ubuntu Server would get rid of a lot of moving parts. The current blocker is that ZFS is not available on gokrazy. Unfortunately that’s not easy to change, in particular also from a licensing perspective."
I don't pretend to get how licensing works, but is OpenZFS and their licensing not an option here? I know its been really tricky with ZFS in general and I don't think its fully answered? but I'm not up to date with it.
Zwave talks on 800-900MhZ and doesn't share medium with ethernet frames, so there isn't a concept of VLANs. Each Device meshes with anything and everything in its immediate broadcast range to provide some elasticity to the network. I can imagine at some high point of devices that the medium could become saturated
