The web is already barely workable, or at least horribly centralised.  The few big companies - Facebook and Google (Alphabet) mainly - are gathering information from users on almost any website they visit due to AdSense, Facebook share buttons, FB's automatic phone setting saying that they'll track your phone activity outside of Facebook, etc.  When not using Facebook or Google, other services in widespread use (like Cloudflare) show that it's becoming harder and harder to run a website really independently.

I think it's a government's responsibility to step in when a monopoly has become so bad it's causing serious damage to society.  There's nothing really wrong with making Facebook pay to use news articles when its services are at risk of becoming a monopoly over the sharing of information (because of the slow death of newspapers).

Alternatively though, the websites could be treated properly as platforms rather than publishers, in which case Facebook should not be curating content for you using their algorithm, nor should they be removing content which is not illegal.  In that situation, it would be understandable for Facebook to claim that they cannot pay for hosting news articles.
