I find the "FP jargon" and "math-babble" to be annoying, but not nearly annoying as the sort of infantilization sites like this engage in. It's a common trope to "dumb down" complex topics into cartoonish explanations, but in reality it only makes the content more confusing, while simultaneously insulting its readers by treating them like children.

No, I don't need a "cartoon intro to DNS over HTTP" to understand basic networking concepts. Nor do I need a story about "Dr Frankenfunctor and the Monadster" to understand functional programming concepts. Even when I was a teenager reading about OOP, I didn't want to read about the "Car class inheriting from the Vehicle class" or the "Dog class inheriting from the Animal class."

When reading technical content, I always prefer prose that treats its readers as professionals, rather than five-year-olds incapable of understanding complexity without resorting to vacuous and incomplete analogies. The problem is that complex topics are complex. By their very nature they rarely fit into convoluted analogies, and would be better explained by simple use cases and examples.
