They didn't like Aaron Swartz's goals (making scientific knowledge more accessible to the public) and they do like the LLM companies' goals (permanently crushing the labor market for knowledge workers)
say what you will about the myriad valid concerns with current LLMs but I personally will never get over the fact that Aaron Swartz was prosecuted to his literal death for downloading JSTOR and then a decade later, they downloaded & ingested the entire world and our IP laws just went ¯\_(ツ)_/¯
