I think the concern is less about a small handful steeping themselves in misinformation and more about what to do when a large chunk of public discourse starts to veer in a tabloid-like direction because such ideas are more captivating and viral than reality, especially with narratives specifically designed to do that being spun ever more frequently by a growing array of parties. Hoping that people think for themselves and practice due diligence only goes so far, particularly when there’s a shocking number adhering to a culture of ignorance and taking pride in not critically thinking or scrutinizing sources.
With that in mind, I can see why a government might want tools to help keep yellow-journalism-like discourse from dominating public forums, but as noted there’s dangers that come with that. It’s a thorny issue.
