Why is it learning anything from any interaction I have with it? Particularly when I have a paid-for agreement with the company that promises never to train their models on my code. Clearly that’s a lie then.

Anyone who believe those agreements are fools ignoring how these assholes make LLMs, by hoovering every bit of useful data they can find, copyrighted didn't matter, likely even less legal sources as well, why would privileged? A system is what it does.
