It explains concepts in a simple manner for beginners and it introduces cool stuff in little steps chapter by chapter.
(It is quite cheap, but probably you could also find the pdf version free on Internet)
And then it hit me, this is just another TED talk style Medium publishing influencer.
Nothing of value here, just a bunch of random OpenCV examples you can just as well find in the official docs https://docs.opencv.org/master/d6/d00/tutorial_py_root.html
Is there new information here? No. But it's presented much differently from the official documentation and perhaps some beginners would find a guide like this less intimidating, more consumable, whatever - people have different learning styles. Maybe the people that would prefer this tutorial over another are a small minority, but I take issue with the sweeping statement that the work the OP put in here created no value for anyone at all.
Looking at their other articles gives me the impression of a content creator that just pollutes the internet for keywords, potentially paid-for.
Just look at https://heartbeat.fritz.ai/ , which this random assortment of code snippets was compiled for, it's all just keyword stuffing as promotion for fritz.ai, plain and simple.
And oh look, nicely delayed submissions of article after article by OP: https://news.ycombinator.com/submitted?id=salma-ghoneim
What you've linked targets a different use case. I don't need to relearn the core concepts through tutorials, and I don't need every possible config option from the docs. I just need simple, easy-to-parse demonstrations of basic use cases. This works for me.

"This" is a bit of an uncharitable way of framing that person, don't you think? Behind those blanket labels is an actual human with feelings and motivations that you and I don't actually know. Handwaving away a person's efforts like this is unnecessarily dismissive, imo. It smacks of "I don't like the motivations I've assumed from you, therefore your output doesn't matter." How would you feel it you were on the other end of that?
I’ve written hundreds of tech articles and dozens of manuals, and I’ll tell you that people don’t want to read. Everyone’s busy. They don’t want a lot of theory or talk about the author’s life. They just want to get the job done. To me this article delivers beautifully on its promise.
