I'm glad that I released my book in 2022 before AI-hype took off. I'm familiar with the type of publisher mentioned in the article too. Those are very strict in their format and content guidelines, and I had also felt that such constraints were limiting at times. I can relate. But, I also learned a lot from the process, and in the end, my book got fantastic feedback. It became one of the print bestsellers in 2022, and got translated to many languages. I've found the whole experience positive.
But, I totally understand author's reasoning, and it's one of the reasons I want to explore different publishers as I want to deviate from writing strictly technical books.
