I don't think the Google case is relevant here, but I definitely think how modern copyright works is really problematic for transformative works like this, fanfiction, (elaborate) reaction videos, etc. Reusing and rehashing creative works is nothing new, but the modern legal customs around copyright really hinders this kind of progress in the arts. The fundamental problem is likely because of issues with the arts under capitalism. Because authors need people to purchase their particular works to make money, royalties by necessity need to be paid and lines need to be drawn over what is "original" or not. This is not the only system that can fund the arts; there is state funding, patron style funding, etc. where authors are not paid on the basis of each individual work, but the collective impact of their works.
