Since the models are not suppressed to answer certain questions and indeed have been demonstrated to be biased toward one end of the political spectrum, and if you treat the model’s output as a knowledge graph, as proposed by John Schulman, one of the cofounders of OpenAI, then yes, I would say the suppression of freedom of speech is a valid argument to make. Otherwise why would there be a set of “uncensored” models that exist in the open source world?
I would suggest you read about these models and think about the implications. Perhaps that’ll lead to you to reconsider your stance
I have done that, and come to the conclusion that "that's business, baby!"
Do you have any more meaningful objections to this "censorship" of a free thing you agreed to license?
