I have not read the SCOTUS order or the case it may refer to, but I did sleep in a Holiday Inn Express last night.
I think the Court says a Google link to a scanned book (by a 3rd party or maybe even Google) available online does not infringe on copyright as a scanned book is not the same as the book/hardcopy as long as you don’t pay money to access the link. What the court seems to ignore is Google makes money on the number of clicks as Google inserts ads on most pages we view or get to via a click.
Meanwhile, the original author and publisher starve.
Sometimes Google searches take me to such scans. I have yet to find such a scan of a work that is still in-copyright without major excerpting. This is the kind of thing that has been deemed fair use because it is far from being a reproduction of the entire original.
I don’t see how this makes the publisher “starve.” In one case I liked what I read so much that I ordered the book from Amazon. That’s a sale that would never have happened had Google not even excerpted the book.
