This case involved copyright, not patents. Copyrights are separate from patents.

Prenda made its money by suing people who allegedly downloaded pornographic films online. Its targets frequently agreed to settlements worth a few thousand dollars rather than facing a courtroom process. These copyright trolling tactics netted the company more than $6 million between 2010 and 2013.

If his strategies had ended up a valid, legal option we would absolutely see trolls expanding into this. John Steele was testing the waters and got eaten by the deep acting as a warning for how not to go about this.
There's some DMCA takedowns and such still, but they aren't quite lucrative enough to show up on patent trolls' radars. Aquila non capit muscas and what have you. A several billion dollar copyright claim like Oracle's passing SCOTUS muster absolutely would have shown up on their radar though.
Prenda is an example of how misuse of copyright is already in the trolls' toolbox.
Since you think about this stuff you might find the latest on the Santa Cruz Operation interesting:

Xinuos is the company that purchased the remnants of the SCO Group in 2011. The SCO Group, in turn, is a company most famous not for its actual products but for its litigation against IBM and Linux. That litigation began in 2003—partially funded by a very different Microsoft, only five years after the leak of the Halloween documents in which Microsoft acknowledged the "long-term viability" of open source software and discussed strategies to choke it out of the market.

The first phase of the case lasted from 2010 to 2015. Oracle successfully established that APIs are copyrightable, but their claims of patent infringement were rejected. Google petitioned the Supreme Court in October 2014 to review the case, but this was denied. A second petition by Google in January 2019 included the judgement that APIs are copyrightable. The Supreme Court agreed to review this part of the judgment in November 2019.
To the degree that SCOTUS has found that an API can be copyrighted, there is still room for copyright trolls to operate.
In particular, social-media aggregators (one app to display your Twitter, FB, Instagram, etc.) may have new protections.
Open source code is still usually copyrighted. Nobody would trust closed languages and APIs unless they paid a fortune for them while open source with a grant would be safe to use.
Java was a mobile OS before Android literally obliterated the market after copying Java. Arguably, if Android was fair use, everything is fair use and all software copyright is fundamentally defeated by this ruling.
He complains about the names of functions being "expressive content". Yeah, "max" and "toIndex" are real expressive.
Also, what the hell is this logic?

The English common law system relies heavily upon judicial precedent. A ruling in this particular case that the copying of an API constitutes fair use will inform decisions in future cases of similar copying.
"Congress rejected categorical distinctions between declaring and implementing code. But the majority creates just such a distinction. The result of this distorting analysis is an opinion that makes it difficult to imagine any circumstance in which declaring code will remain protected by copyright."
I concur with Thomas (not in the connotation - he thinks this is a bad thing, I do not - but in the denotation). This ruling is such strong precedent that almost any API cannot be bound by copyright that no company is going to be willing to spend the money to raise the question.
In this particular case, Google's copying of interfaces was ruled to be fair use because its purpose was to allow Java developers to reuse their skills. This reasoning only holds for the declaring parts of the copyrighted work though. And that's why the distinction becomes necessary even if Congress rejects it as a primary distinction between copyrightable and non-copyrightable work.
That's also why I think the ruling is perhaps not quite as broadly applicable as some (including Thomas) are thinking right now. It may not cover code that isn't used by a significant number of developers. I haven't read the entire ruling, so I'm not sure whether it covers non-public interfaces that are nevertheless useful for interoperability. Such interfaces were at the center of past disputes (I think Microsoft's SMB protocol was one such case).
Or prevent them from eradicating competing or even original projects by doing hostile rewrites or forks?
Wouldn't this directly contravene the findings in this case?
