Furthermore, the prompts are designed in such a way that avoiding DCC involves hitting no/cancel/decline on the left side of the screen whereas accepting DCC has language such as next/continue/yes/accept/ok on the right side of the screen. This is usually after a few prompts of hitting "yes", so the designer of this user interface already has the user getting to hit next/continue/yes/accept without thinking about it. It's absolutely sickening, and the vast majority of people fall for it and they never know they got screwed.
