There is still a question on fair use. Google won the jury trial, but the appellate court is ruling in a few months, and that could change everything.

The link that you provided is from May of 2016. AFAIK, Google won that case and the appeals and there are no ongoing appeals: https://en.wikipedia.org/wiki/Oracle_America,_Inc._v._Google....
