What data do you think DDG has on you now, that they could sell? Or is your concern that DDG could cell out on the promise of users, and that users would fail to notice a change in privacy-respecting behavior?
Precisely, yes. As with all internet services we can't really audit what's being collected as simple users, we have to trust them to "do no evil". If tomorrow ddg started logging my browsing history in order to better target ads for instance I probably wouldn't notice a thing.
