Anti-scraping measures people utilize are neither unethical nor illegal. That’s the difference.
They could detect the other AI labs and also silently burn the tokens at a faster rate providing fewer tokens for money, which does sound illegal to me.
The comments only further prove that without more regulation around this, big AI wouldn't have a "don't be evil" attitude going forward.
