I agree, it's going to be tough problem to navigate. I can't even come up with a vague ideological solution for it, let alone a good mechanism that is fair and robust against corruption. It's like being stuck inbetween one ideal and another. Freedom of information vs stopping the bad being caused by misinformation.

My optimistic side would hope that putting education in schools about misinformation and how to critically think about and analyze journalism could at least help the issue.
