"It's what the article is about. Did you read it?"
Arranging a course so that your students never struggle with the material is one thing. Never bending to your students' needs, as a teacher, is another. A teacher can provide a lot of opportunities for the students to struggle with the material. But I think it's ridiculous (and lazy) to teach without any regard for pedagogy, especially with high school students.
I know exactly what the point of the article is. Thanks for asking.
By the way, "cautiously [guiding them] through every problem in life, or in education" communicates a very different thing from "[putting in] more effort to make classes "fit" a student's preferences".
