The point is the author of the blog is spreading FUD by saying "you can't leave your Yubikey unattended because anybody can take it and use it to SSH without your consent".
That is a falsehood and deserves to be called out.
I don't mind "revolutionary ideas", but don't use your platform to spread FUD.
It's great to correct falsehoods, but please do so without "calling out". The online callout/shaming culture has toxic effects and we're on a different trip here, or trying to be.
