I agree with the comment and find the linked article motivated reasoning at best. It's easy to find something "morally good" when it aligns with what you wanted. But plenty of people at Oracle, at IBM, at Microsoft, at Nintendo, at Sony and plenty of other companies whose moats have been commoditized by open source knockoffs don't find such happenings to be "morally good". And even if in general you think that "more freedom" justifies these sorts of unauthorized clones, then Oracle V. Google was at best a lateral move, as Java was hardly a closed ecosystem. One also wonders how far the idea of "more freedom" = "good" goes. How does (did if Qualcom's recent acquisition changes the position) the author feel about the various chinese knockoff clones of the Arduino boards and systems? Undeniably they were a financial good for hobbyists and the maker world alike, and they were well within the "legal" limits, and certainly they "opened" the ecosystem more. But were they "good"? Was the fact that they competed and undersold Arduino's work without contributing anything back and making it harder financially for Arduino to continue their work a "moral good"?

If "more freedom" is your goal, then this rewrite is inherently in that direction. It didn't "close" the old library down. The LGPL version remains under its license, for anyone to use and redistribute exactly as it always has. There is just now also an alternative that one can exercise different rights with. And that doesn't even get into the fact that "increased freedom" was never a condition of being allowed to clone a system from its interfaces in the first place. It might have been a fig leaf, but some major events in the legal landscape of all this came from closed reimplementations. Sony v. Connectix is arguably the defining case for dealing with cloning from public interfaces and behavior as it applies to emulators of all kinds, and Connectix Virtual Gamestation was very much NOT an open source or free product.

But to go a step further, the larger idea of AI assisted re-writes being "good", even if the human developers may have seen the original code seems to broadly increase freedoms overall. Imagine how much faster WINE development can go now that everyone that has seen any Microsoft source code can just direct Claude to implement an API. Retro gaming and the emulation scene is sure to see a boost from people pointing AIs at ay tests in source leaks and letting them go to town. No our "foreparents" weren't competing with corporations with unlimited access to AI trained on their work, they were competing with corporations with unlimited access to the real hardware and schematics and specifications. The playing field has always been un-level which was why fighting for the right to re-implement what you can see with your own eyes and measure with your own instruments was so important. And with the right AI tools, scrappy and small teams of developers can compete on that playing field in a way that previous developers could only dream of.

So no, I agree with the comment that you're responding to. The incredible mad dash to suddenly find strong IP rights very very important now that it's the open source community's turn to see their work commoditized and used in ways they don't approve of is off-putting and in my opinion a dangerous road to tread that will hand back years of hard fought battles in an attempt to stop the tides. In the end it will leave all of us in a weaker position while solidifying the hold large corporations have on IP in ways we will regret in the years to come.
