I guess I don't understand what is so deceptive about this? At least not anymore than what Google does for example?
Do we really think computer illiterate people know that Google can infer a huge about of sensitive information about their end-users without them ever ticking "i accept" or signing up for an account?
At least with this they have to take explicit actions like accepting the terms and installing the tracker before they're tracked. They even get compensated for it.
In Google's case you don't get anything.
