This is not a partisan issue, when you start down the road of handing the keys to shaping public thought to a powerful party, you're there when the power changes too.
This is no different than being able to tell when someone is bullshitting just as you walk through every day life, and thinking we need to shield the poor naive populace from harmful ideas is borderline stereotypical paternalism.
This is all obviously a big deal to old media, who have made an art not out of sharing incorrect truths, but of very selectively sharing truths, to the point that what emerges does not really represent the truth at all. They didn't lie, but they aggressively shaped. Of course democratic access to the pieces they'd rather suppress (on both sides) threatens that model. They'd love us to toss out this particular bath water.
