Also consider that Thomas and Alito dissented in the Google/Oracle ruling, and wrote something inflammatory, to the effect of it being unreasonable that Google was being allowed to infringe upon Oracle's copyrighted code (by implementing a compatible API). And that was before the Supreme Court was stacked with more like-minded people.
Not having sensible people steering copyright in a direction toward winding down its scope is being paired with a court that's likely to make it far more draconian, and create some massive problems that will be a problem for software development.
