Earlier quoted context omitted.
A lot of products are returned in used state, or have very slight use marks like scratches, tiny dents, protective foil that's been removed, etc. These items therefore can't be resold as new. Finding out exactly which items are and are not good enough is expensive, and therefore the items are just discarded.
>About half of the items marked for destruction were still in their shrink-wrap, while the other half were returned items in good condition, they said. They're destroying new products too!
The article is heavy on implication and light on facts.
They are destroying things for a reason, which isn't given. It could be a bad reason of course, but probably isn't.
