Are you trying to argue that 10 years ago when I uploaded my resume to linkedin, that I should have known it'd be used for AI training?

Or that teenager that signed up to facebook should know that the embarrassing things they're posting is going to train AI and is, as you called it, public?

What about the blog I started 25 years ago and then took down but it lives in the geocities archive. Was I supposed to know it'd go to an AI overlord corporation when I was in middle school writing about dragon photos I found on google?

And we're not even getting into data breaches, or something that was uploaded as private and then sold when the corporation changed their privacy policy decades after it was uploaded.

It's not a bad analogy when you don't give all the graces to corporations and none to the exploited.
