I would also argue that unfettered access to incorrect information is also a massive problem for democracy.
Unfettered access to information requires unfettered access to incorrect information. The power to decide what's "correct" will be abused to block correct information that damages someone powerful.
We live in a world where the authority we defer judgement to has split up, into less balanced partisan entities. Not saying pre-internet news were unbiased, but public sources tended to be better curated. (At least where I live, I'm sure Fox has always been this horrid)
This is why filter bubbles and building psychological profiles for everyone to target them with political messages and free access to all information, correct and incorrect, does not work. It's a net negative to democracy and this neo-greek ideal of the marketplace of ideas is a sham.
