Preserve the author's way of expressing ideas
Word choice, sentence rhythm and tone should reflect the individual expert, not turn their thinking into polished but interchangeable prose. In "How a Coffee Chain Helped Me Make Peace with AI", the writer describes asking ChatGPT to rewrite the article and finding words and turns of phrase that did not feel like their own. The practical distinction is between making writing clearer and replacing the author's voice. Edit language, rhythm and word order to match the person whose thinking readers are encountering. "Cut the jargon: The best B2B writing is plain and simple" makes a complementary point: knowledgeable audiences do not require a performed "expert" voice. Stay honest and true to the message without making the author sound more formal than the ideas require.
