The ready availability of Arduinos and similar technology has brought a lot of people into that scene who are not aware of what all is available to them, what all the bits and bobs are, and what you can bash together with a few resistors and capacitors hooked up correctly. People like me. I think I can call myself tolerably good at programming, but I can easily tell I'm much more newb at EE and I can really only operate with things that have clearly defined outputs that match up to some other input. Where you may see trivial conversions you could bash together in your sleep, I see an output that doesn't match the input and don't immediately know where to go with that. In my case, I'm able to follow the post just fine, but if I had to put that circuit together from scratch from first principles I'd be looking at weeks of learning more about EE. And as a result, as I am blundering about an unfamiliar landscape in some personal projects I've got going on, I appreciate posts like this.
