I admit a scenario in which you have to communicate everything that the abstract communicates is kinda contrieved, though it could happen if the article is the main target of your discussion. But in general, pointless paraphrase of other sources is widespread.

>Summarizing another academic work in the context of your own work is a bedrock activity in academic thinking as well as writing.

Summary has its place, but paraphrase is another thing. Quality of paraphrase is defined by surface-level features like vocabulary, grammar, and re-arrangement of sentences, and second-language English education often fails to advance beyond word-by-word substitution. Even when the exercise of paraphrase demonstrates some kind of understanding of the original text on the part of the author, it doesn't necessarily aid the reader.

I'm not trying to deny that tortured phrases may also indicate paper farming and plagiarism btw, just saying that there are other factors.
