FWIW, I know iOS's camera natively detects QR codes, and I believe Android does as well. In my opinion, the ability to use the native camera app to read a QR code significantly reduces the barriers-to-read for general users
Absolutely game changing for the technology! And very convenient too
Nowadays it seems anything that can do something FOR you usually does something TO you.

Or is it extra safety to use the CLI? Arguably it is easier to verify that a webapp is not sending the data to a 3rd party, than it is to verify that the CLI tool doesn't (easy network inspection from the developer tools).
It’s easier to verify the CLI tool, since it wouldn’t be available in my distribution’s repositories if it contained phone-home code.
Most ISP put this kind of QR code on the provided "modem" in France with the default Wifi password of the device. I love QR code. I think it should be everywhere. All legal documents and forms should have one. All supermarket bills should have one. It's a fantastic way to transition from paper to bits. Unfortunately most users have no idea what it is. They don't know what a URL is, so a QR code is out of the question…
Have you been to China? QR—everywhere.
They are not generic QR codes, but encoded instructions to access specific in-app features in WeChat/AliPay. If you scan those special codes with generic QR readers, you get invalid URLs.
IMO this makes it even worse to use generic QR codes, because if a QR code cannot be parsed by WeChat/AliPay, most Chinese users do not know what to do with it.
