Most young folks don't understand URLs anymore? "Find us on App Store" or "Find us on Social Media" is the new internet. QR codes that takes you directly into a walled garden is the new web.
Id argue that QR codes are doing pretty well at keeping bespoke URLs alive (although it pains me to see people use qrco.de or other qr code generators that automatically shorten the URL and thus could, at any point, maliciously redirect people to ads or malware instead. I don't see bitly doing this but it's unnecessary risk).
