This extends to review articles as well. 20 years ago there used to be magazines that reviewed products by actually using them. There were also users reviewing products and there were websites where these personal reviews were aggregated

Nowadays all review article just work off the specs without using and testing the products. And the user reviews have moved to Amazon, which are mostly very poor quality or just fakes, or possibly reviews for other products. In any case, there are no incentives to give high quality reviews of products, and google seems to have no incentive to show me the few remaining real review blogs.
