---- New look "Google Knowledge" replaces results with content

"Public domain" is a legal term associated with copyright law. It has nothing to do with availability, distribution, accessibility or similar.
To a search engine, where its defined purpose is to help navigate end users to specific websites, the use of snippets can be described as fair use even if that snippet provides a short and concise answer where attribution is supplied. Google has a history of treating everything as public domain, which is not specifically blocked, and uses it in such a manner that limits individuals from visiting the origin website. Google Images comes to mind, and I'm sure there are a few around here that will have their own opinions on that subject. Knowledge Graph is no different as I believe it will morph into another content grab by Google.
Regardless of what a search engine may or may not display, their intent is the core issue I have a problem with. While all outbound links on their search page are blue, why has Google chosen to use a more subtle gray? Will it increase the ctr to the websites where the information originated from? No. It's intended to use the content of another to keep people on a Google property. What's next, a 1px attribution link?
