A QR code by itself is completely unreadable to a human. Can't this have the SSID / password too? All too often you see what should be simple textual data wrapped in this obtuse form which only specific machines can read. Text and a QR code can be read by everyone.
This is misuse of QR code; QR codes should be used to encode large data or some other clunky data that is hard for people to process that's why it is easier to look up such data/information with QR code and process/read it digitally. After all you have a camera in your pocket and a preinstalled QR code scanner(at least all new Android phones have). The main use case of QR codes that I see is simply linking you to a website. For example your favorite food brand links you to their website to explore their offering.
>Text and a QR code can be read by everyone.
Yea I agree with you that both plain text and a QR code should be shared so people can use what suits them the best at that particular moment.
Agreed. Where I used to work, IT started replacing the guest wifi (password changes monthly) with QR code instead of printing out the password on a piece of paper. It's really cumbersome when I want to join on my laptop.
