I'm not sure if it should be done by the governments, but there is a huge freedom vs responsibility imbalance in broadcasting: you can reach millions of people with well crafted misinformation easily with zero responsibility, and social media algorithms actually promote misinformation as a side effect of optimizing for engagement: truth is boring. I don't think it will get fixed in any way: there is too much money to be made. Paraphrasing Leni, we will hang ourselves on the rope that we sold to ourselves :)
