That is fearmongering tho.
QR are links (sure, they are more complex and the simple act of scanning and decoding can be an attack vector, but so is receiving a message with some IM apps), and are no more malicious than links.

They are also a convenient way to encode information that the user should not have to type.

So yeah, everyone should use caution while operating a connected device, but hating QRs is scaremongering, and it'is stupid too.

Don't do that.
