The last time this policy was threatened (by Belgium?? IIRC) Google merely cut those websites completely out of the search results. In a matter of weeks those websites were seeing their internet traffic drop to practically nil.
It seems like Google disabled excerpts to news sites in France back in September 2019 leaving the search results only with the headlines/titles of news pages. What the French do there sounds incredibly unfair and I am certainly not a fan of Google.
There is a side-question about this, are search engine even legal at all, by violating copyrights by publishing excerpts of websites (or full content like lyrics) in their search results without owner consent.
