The top comment's also pretty good, especially the final paragraph:
I guess these companies decided that strip-mining the commons was an acceptable deal because they’d soon be generating their own facts via AGI, but that hasn’t come to pass yet. Instead they’ve pissed off many of the people they were relying on to continue feeding facts and creativity into the maws of their GPUs, as well as possibly fatally crippling the concept of fair use if future court cases go against them.
It was a pretty good comment, and pointed out one of the possible risks this AI bubble can unleash.
I've already touched on this topic, but it seems possible (if not likely) that copyright law will be tightened in response to the large-scale theft performed by OpenAI et al. to feed their LLMs, with both of us suspecting fair use will likely take a pounding. As you pointed out, the exploitation of fair use's research exception makes it especially vulnerable to its repeal.
On a different note, I suspect FOSS licenses (Creative Commons, GPL, etcetera) will suffer a major decline in popularity thanks to the large-scale code theft this AI bubble brought - after two-ish years of the AI industry (if not tech in general) treating anything publicly available as theirs to steal (whether implicitly or explicitly), I'd expect people are gonna be a lot stingier about providing source code or contributing to FOSS.
