Shifting the guilt to the consumer is an intentional marketing ploy. The same was done when soda companies switched from bottles to cans
Originally soda machines had a place for you to return your bottle which the company would collect, sanitize, and re-use. Consumers paid a deposit when they bought the soda, then got it back when they dropped the empty bottle in the slot. Bars and restaurants also had to pay the deposit and redeem the bottles for a refund
Then companies decided it’d be cheaper to use disposable aluminum cans. Soda is something people often consumed in public places like parks and in front of stores. Increased public trash led to a litter problem. Environmentalists pressured the soda companies to fix the problem by bringing back the deposit and recycling programs. Instead, the companies started anti-liter campaigns that placed the guilt wholly on the consumer
This was decades before curb-side recycling existed. Recycling plants were few and far between, and consumers would have to save up cans then cart them to one of these facilities to recycle them, which few individuals had the time and transpiration to do. The ad campaigns led to people demanding more public garbage cans, which did reduce liter, but those were purchased and maintained at city expense and the contents went to landfills. It also led to the general public believing littering and landfill problems rested squarely on the shoulders of consumers even though the corporations had a perfectly good recycling system that they could have continued
Big business wants you to blame yourself and each other for problems they caused, and they’d rather spend money on guilt shifting ad campaigns than use that money for something good
