either they corrected the issue or Mario got something wrong, ChatGPT gave a detailed answer when I asked it about Suchir Balaji.  Here it is:

Suchir Balaji was an artificial intelligence researcher who worked at OpenAI from 2020 until August 2024. During his tenure, he played a significant role in gathering and organizing internet data used to develop models like ChatGPT.

In October 2024, Balaji publicly expressed concerns that OpenAI's data collection practices violated U.S. copyright laws. He argued that using copyrighted material without permission to train AI models was both unethical and illegal. In an essay titled "When does generative AI qualify for fair use?", he analyzed the outputs of large language models and concluded that they did not meet the criteria for fair use under U.S. law.

Tragically, on November 26, 2024, Balaji was found deceased in his San Francisco apartment. The San Francisco medical examiner's office determined the cause of death to be suicide. However, his parents have disputed this conclusion, citing contradictions found in a private autopsy they commissioned, and have called for an FBI investigation into his death.

Balaji's revelations have been significant in ongoing legal debates concerning the use of copyrighted material in training AI models. His insights have been referenced in lawsuits against OpenAI, with plaintiffs alleging unauthorized use of their content. OpenAI, for its part, has defended its practices, asserting that their AI models are trained on publicly available data in a manner protected by fair use and related principles.
