There's a good article on the GNU project website that talks about copyright: https://www.gnu.org/philosophy/misinterpreting-copyright.en.html though there are many other writings on copyright from a socialist perspective. (disclaimer, author is a bernie bro libertarian)
Essentially copyright acts as a mechanism for the bourgeois classes (publishers, media conglomerates, large firms) to siphon and hoard works for themselves. Initially the system was germane but as patent and publisher lobbying groups grew under capitalism, the system of copyright, patent and trademark law all were lobbied to favor publishers more highly than both authors and readers (the infamous "Mickey Mouse" law was used to extend copyright past a regular human's average lifespan, essentially enshrining artistic works as permanent private property.
In a socialist society, copyright would be essentially done with as its main purpose was to "protect" (big air quotes here) the profits of publishers. If every author and artist had a guaranteed salary and training, copyright would not be needed. Note that copyright is explicitly not the same as attribution. A sad example of this is how many manga artists in Japan (a global north country that is infamous for draconian copyright enforcement) actually don't hold the copyright to their works. For example, the creator of One Piece (a series which grossed hundreds of billions of dollars in its 2+ decade span) doesn't actually "own" One Piece, Shueisha, the publisher, does. The mangaka is simply an employee hired by the publisher to produce authorized content of said series.
Today we have what we call "copyleft" licenses which were coined by Richard Stallman back in the late 80s which use copyright laws and flips them on its head, allowing for the work to be collectively owned. The GNU General Public License and Creative Commons licenses are both examples of copyleft licenses.
