Looks like most of us saw the same items.
We could beat this thread to death though, but the issue is still one that relates to "existing" versus "new" installations.
I would recommend that the most recent rules be considered, and re-identify the white wire as a hot leg, and use the equipment bonding jumper to the switch, where is is connected to the equipment grounding conductors in the box if any do exist.
That requirement is not new, and has been a requirement in the code for quite a few code cycles, it's the issue about the metal plate that is new.
What happens when something goes wrong with the advice given, and someone gets hurt or there is some property damage?
Sparky's tools are really funny and they seem to be just what the "unqualified person" would use.
