The US Judge did rule that displaying snippets is "transoformative" and permitted under fair use guidelines.
Again: Facts, data, and ideas aren't protected by copyright. Whether the Knowledge Graph is "transformative" doesn't come into play, at least for the Knowledge Graph examples that I've seen.
Many site owners have the naive idea that they (and only they) have the right to display raw information that's in the public domain. If they find the symptoms of a cold on CDC.gov or WebMD and list those symptoms on their pages, it's OK, but if Google does it, it's a sin. Sorry, folks, but what's good for the goose is good for the gander--and copyright law is what it is, not what you might want it to be.
