Many of them seem to be written/edited by people who are more interested in using an equation editor than in trying to explain the topic. I don't necessarily expect ELI5 level but I wonder how many people who don't already understand the topic in depth can decode most of those math pages.

They dive into a lot of jargon and rarely attempt to provide any real context that a non-specialist can understand.

I understand that it's hard to do and it also reflects the fact that Wikipedia pages are wildly variable in the audience they're written for.
