The issue of consequences of data leaks, though real and something I find outrageous, is orthogonal to this discussion. When talking about sending personal or sensitive data to AI companies, people are not worrying about data leaks - they're worrying about AI company doing some kind of Something to it, and Somehow profit off selling their underpants.

(And yes, no one really says what that Something or Somehow may be, or how their underpants play into this.)

sorry I did not mean leak, I meant “leak”

people should 1,000,000% be worried about AI company doing something kind of something with it which they are doing as we speak and if not now will be profiting soon-ish
