When you talk about likes and dislikes, generalisations do really fall down. For example I have indeed seen code rewritten from scratch because the programmer did not want to spend the mental effort to understand it and liked doing their own thing. I have also seen code re-written from scratch under the greatest reluctance because the original code was so broken.

Generalisations are all very well when they have something to teach us. In the article's case neither the thesis nor the counter-thesis seem particularly illuminating to me.
