I think the comment is more directed at folks who, and I noticed this weird behavior the other day myself, post tirades about the cardboard box being slightly damaged (while the goods and packaging inside are completely fine).

The behaviour you describe would be considered normal in Japan. There it's not a sub-culture. Pretty much any Japanese buyer would consider the packaging as part-and-parcel. And they'd complain in case of defective packaging, regardless of its functional impact.
As someone who lives in Japan that’s a behavior that a loud minority of unreasonable people exhibit, but most Japanese people I know don’t mind damage from transit like most well-adjusted humans anywhere - the delivery person might point it out when you sign for the package but it’s not a big deal. It’s more important for gifts and stuff though where the presentation is part of the gesture.
