Someone I know actually got access to some stuff this way before; got access to a gold mine that was supposed to be private but someone misconfigured the webserver.
[a]: legally use
The most you can do is inform the owner that their data isn't protected. And even that, unfairly IMO, is legally dicey.
but the parent was not putting constraints on how i obtain it ('somehow learns those facts'). if the publisher makes a mistake and i hit the URL and the data is automatically downloaded, i didn't do anything wrong. doubt i can then just use that information though?

"On June 13, 2013, in the case of the Association for Molecular Pathology v. Myriad Genetics, Inc., the Supreme Court of the United States ruled that human genes cannot be patented in the U.S. because DNA is a "product of nature." The Court decided that because nothing new is created when discovering a gene, there is no intellectual property to protect, so patents cannot be granted. Prior to this ruling, more than 4,300 human genes were patented. The Supreme Court's decision invalidated those gene patents, making the genes accessible for research and for commercial genetic testing."
This is the nail in the coffin. Imagine the lengths lawyers would go if they could monetize any abstract reference to something.
