In my field, at least, I think the problem is less about the medium, and more about the incentives. Researchers are incentivized to write papers that seem impressive (and intimidating) rather than clear and intuitive.

To make matters worse, this is an evolved trait: researchers whose papers are intimidating are more likely to succeed, which means they're more likely to have future PhD students, which means that the style of writing is more likely to get passed on.

I think the main way to address this is to change the incentives. In particular, by creating publication venues that value simplicity and clarity (one such conference is SOSA, which has had a lot of impact on theoretical computer science in the last few years).
