I also don't understand the reason but this is my experience on 80% of the internet basically. Articles that purport to share how to do something then spend most of the article talking about stuff I don't care about, then we finally get to the complicated part then they skip some detail or use some library that I don't want to use and then they're just like "bam it's done! woo"

Those articles are just using the same examples (often verbatim) from the official docs. It's obvious that the authors haven't actually developed anything themselves.

There may be a lot of quality material out there, and it's just hidden under the mountain of low effort scraped, copied & AI content
