I think researchers could make their work very accessible to the public while still publishing in high impact journals. Unfortunately it would require a lot of extra work and wouldn't really do anything for their h-index or future job prospects so there is a lack of incentive there.

It's nothing to do with your second sentence
You can't publish in more than one place because it breaches copyright and breaches several scientific ethics codes.

And most of us deliberately keep our stuff out of the mainstream press when we can becuase idiot journalists/press offices misrepresent what we say.
