You'd have to read the book. He uses "you don't stand a chance" in the context of will power.

That is, in short, (and I'm paraphrasing): ...Some of the brightest human behavior experts in the world are being financed by some of the deepest pockets in the history of the world to influence your (read: our) behavior... Just use will power? You don't stand a chance.

The "defeatist" to me is, "I don't have anything to hide." That might be true, but those influence super powers are going to use that "nothing to hide" against you.

Read the book. It's just over 100 pages. It's on the order of "The Age of Surveillance Capitalism" but that book is 500+ pages. THoSC is great but it's a serious commitment.
