Earlier quoted context omitted.
>it's almost more of a "plagiarism" case than a "copyright infringement" Do you know what the definition of plagiarism is? Google it, "copyright infringement" is listed as a synonym.
Actually, plagiarism and copyright infringement are different things. For example, it is possible to plagiarize something that is not copyrighted, and many forms of copyright infringement wouldn't fit the definition of plagiarism.
Of course, in academia paraphrasing is still plagiarism, but it is likely no longer copyright infringement especially in this case.
