Theres a growing pop-math trend on youtube but for the most part I reckon the lack of accessible language is at least in part due to the assumption that no one would bother reading the article in the first place without certain familiarity with the topic.
Also it is innately difficult to describe concepts from pure math in regular everyday language, hence why notation was developed in the first place. Try describing a polynomial or the properties of a deferential equation without using anything other than normal everyday language. You probably could, but it would certainly prove challenging. And there are other concepts that simply cant be explained any simpler than they already are, but it requires prerequisite knowledge to be meaningful.
