Yea a QR code is only marginally better than requiring an app. I shouldn't need a goddamn smartphone to conduct business and live in society!

The actual reality is that it's impossible to have people go to a web site from a physical ad/offer/thing without using a QR (or paying Google). Google (and friends) managed to hide the URL almost totally, people don't even know that you can go somewhere without searching on google. So the options are: paying google to have your name point to you (an expensive choice depending on the actual name) or use a QR. Weirdly enough people uses QRs this way. I think the restaurants/bars menus after the pandemic only digital via QR opened this way (again, it was trendy also many years ago).
