"Meta to end news access in Canada over publisher payment law".
Summary: Canada passed a law requiring search engines and social media companies to pay news organizations for the right to post links to their stories.
Meta/Facebook (and others like Google) said, "No, we will just not allow posting news stories onto our platforms if you are viewing in Canada".
Canadian news agencies (like CBC) and government officials are mad, and pulling their advertisements from Meta/Facebook.
FWIW, the Columbia Journal of Law & The Arts calls the Canadian law "remarkable measures on the basis of a mix of questionable assumptions".
In the US, California is considering a similar law which "would essentially tax the advertising profits platforms make from distributing news articles. Under the measure, some 70% of the money collected from the so-called 'usage fee' would support newsrooms throughout the state".
Facebook/Meta said if the CA law passed, they would also pull news access in California as well.
