It's easy to figure out what the authors are saying, provided that you guys have something called "basic reading comprehension". Here's a TL;DR: "software is being judged by the wrong criteria. Focus on the users, dammit. Software should be judged by its usability, speed, bug-freeness, and innovativeness." The authors aren't really picking a bone against structured programming (or object-oriented programming, or whatever), those bullet points sound more like the type of excuse for crapware that you'd hear back in the day.
Also look at the references; the newest one is from '94. This text is probably from '94-'00. Tech reference there should be contextualised to those times, not to 25~30 years later aka now.
Finally, the general tone being used by the text is not serious, it's cheeky and troll-ish. Odds are that the authors intended this as food for thought, not as a dissertation that should be analysed and replied with "ackshyually, this specific example is 0.573% inaccurate lol lmao".
