I wonder if this has to do with superhero comics being popular in a particular era, let's say the 80s-90s, and most of it's fans getting into comics around that time, and sticking around. I admit, I did try to get into comics a few years ago, during the peak MCU craze, but I found both Marvel's and DC's offerings, with hundreds of characters who stories run in parallel and intertwine in a confusing fashion over hundreds of issues over decades to be impenetrable. I suspect newcomers struggle with the same issue, while for die-hard veterans, it's part of the core appeal.
