It doesn’t even need to be specifically targeting the U.S. Canada should require all media operating in Canada with a physical presence should have that physical presence have Canadian majority ownership/controlling interest. That is (I believe) enforceable as well as non-discriminatory and fully justifiable as a matter of national security.
At least the effort diminishes over time. There are a lot fewer mainstream journalists than articles.
I would like to see more non-profit effort into making this information plainer and more accessible, in a way that has wide reach yet doesn’t depend on media cooperation. Heavily promoted robust (and free) browser extensions, for example, that can parse out publication and author and will automatically show terse bios, or autogenerate (or select from a comprehensive bio) author/publication background information relevant to the specific article. The signal-to-noise ratio has to be super high so a tiny amount of additional information is highly informative and also pervasive.
Tools like Ground News or the 3rd-party publication rating systems don’t go nearly far enough and don’t have enough reach nor reduce user effort enough.
