alt Hacker NewsIt's primarily relevant because it makes scraping search results much more expensive, solidifying Google's effective monopoly on Internet search.
Google has previously tried to prevent scraping of search results using legal means, but courts correctly think that scraping of Google's search results should be legal, just as Google's scraping of the whole Internet is legal. This is Google's reaction to that.

You can opt out from Google scraping you though? In theory you can opt out of anyone scraping you (if people were well behaved). Google should get to opt out of being scraped too.
This is the best explanation. They’ve been doing the same in Google News. Each entry comes not with a URL to the source, but with a hash. To resolve it, you must send requests to Google’s servers. Anyone who wants to create a list of URLs of sources automatically can therefore be blocked by Google now on two levels rather than one - the search for a list of results, and identifying the source URL for each result.
In effect, they’re removing attribution from the content they quote from other people’s websites. It would be interesting to see if courts object to that. It is one thing to crawl other people’s websites and display snippets of their work as your search results when each result is properly and transparently attributed. But if the text is quoted and the source is not there alongside it in plaintext, replaced only by a vague promise that, if you ask, we may or may not tell you where this piece of content is from, that is a very different deal.
