The following discusses copying an item that is being sold by its creator (https://torah.org/learning/honesty-class64/)
Rabbi Moshe Feinstein ztl said that it’s not permitted to copy any item that is being sold by the creator of that item. Every time you copy it, you’re taking away sales from him. Anybody who downloads it, copies it, or does something else is really just turning someone else’s money into ashes. And that’s really the bottom line. It’s taking something from someone else.
How does this apply to items that one would be likely to buy from a third party in used condition?
What if the creator still sells the product himself, but it is unlikely that one will purchase it directly from him (such as an uncommon book, a foreign film, etc.)? What if the creator no longer sells the product but still holds the rights to it? What if the creator no longer holds the rights?
