I believe there’s a lot of confusion around the term “ownership”. There just might not be an answer because nobody ever “owns the copy”. As HN is quick to point out when discussing ad blockers or scihub, data isn’t a thing that you can own. You may own the physical medium, and sometimes said ownership is linked to a license (first sale doctrine, as one example), but it isn’t necessarily so.
Per US Code §117, which Cantrill links to, there is a concept of "the owner of a copy of a computer program" (direct quote from the law). So that can't be right.
