Is Google Prioritizing YouTube and X Over News Publishers on Discover?

"The changes could be devastating for publishers who rely heavily on Discover for referral traffic. And it looks set to accelerate a global trend of declining traffic to publishers from both Google search and Discover."Xavi Beuma
