This is such a big part of it and it's amazing that they get away with it.
Case in point: Blue Apron. Blue Apron positioned itself as one of the more "recycle-friendly" food delivery services to try and fight the stigma against every delivery having bags upon bags of individually wrapped goods by providing recycling services. As a former Blue Apron customer, I loved that I could separate stuff out (hard plastic, soft plastic, paper, etc.) and throw away anything that touched raw meat and just send it back to them in the same cardboard box I received it in.
Blue Apron then cancelled their recycling services and now just redirects people to do it themselves because "recycling is hard". Now, the number of people that will actually recycle will drop further and Blue Apron doesn't have to change its operations one iota. I cancelled my subscription as soon as they removed the recycling options because they wanted to put the blame on the end user instead of themselves for producing all that waste in the first place.
There is a solution here. Until it's financially incentivized for them to find it, though, we'll be stuck here creating more and more waste.
