It provides no value to the discussion, doesn't make any interesting points, and tries to emotionally manipulate the reader. Funny enough this applies more to your statement than the statement you're responding to. They were making a meta-critique of the general discussion here, and I find it to be a legitimate perspective. Personal sentiments on liking or not liking QR codes, which any lay user can make, does not make as interesting a discussion as a principled approach to what components of the UX flow exactly fails, whether these failures are essential to QR codes or specific to the implementations today, and how/if they could be addressed as an engineering exercise. It is akin to saying "this first gen ICE automobiles suck, bring back horses" and go on to discuss the annoying doors of the car while the unexploited fertile land of discussions await on the actual engine, cost benefit analyses, incremental improvements, adoption barriers, UX flows etc.
