I agree with you. To put it simply, papers are optimized for the scientific community and making them "more accessible" to outsiders has a cost. I'd settle for better writing and presentations within the scientific community for now. If you ever find researchers that blog about their research in simple terms, I think it's safe to assume they're using their personal time to do that (I know of very few; Andy Ko [1] comes to mind).
