I really like and admire @pluralistic and have utmost respect for him, and that's why I'm totally baffled about why he is claiming "fruit of the poisoned tree" arguments as cause of LLM scepticism.
The objections to LLMs aren't about origins but about what they they are doing right now: destroying the planet, stealing labour, giving power over knowledge to LLM owners etc.
The objections are nothing to do with LLMs' origins, they're entirely about LLMs' effects in the here and now.
