You're misinterpreting that report. All it tells us is that Google returns results the user doesn't want to click on more than half the time. We can't determine whether that's for positive reasons (eg info in the results page) or negative reasons (eg the results were garbage) based on the fact there wasn't a click.
I personally hate Google including say Wikipedia snippets. Quite often I want to read more of the article, and the link is small and at the bottom of the box, often requiring you to click and arrow to reveal the full box.
If they value Wikipedia and Genius/MusicMatch so much, they should make it much clearer where they got their content from.
Whenever you search for song names they take the first two pages and interesting stuff such as news and interviews are scattered around the rest of the results.
Allow power users to pick a default, so we don't have to suffer through terrible third party content and ads.
Disabling this functionality will be a net negative for the end user.
I get why this is included in Anti Trust but I love this feature. Recently read a report that now <50% results lead to click which means it is loved by lot of users too.
