Can you prove that the old media is any less biased and politically funded than the new one? That they actually were more politically neutral and valuable?
Clearly old media is a mixed bag. Some do spread misinformation, and those seem to be the most popular outlets today.
But there is a third possible solution: sue the spreaders in civil court. Example: Fox News in October 2020 paid out millions to the family of a dead DNC staffer about whom Fox had repeatedly spread incendiary and false stories.
Of course, some people will say the courts can be biased...
