That is certainly one element of it. I also want to highlight, though, that oftentimes data is collected from people without their consent. So many people who use the Internet to shop or to search for information don't know how they're being tracked.
As I mentioned, face prints being captured are often captured without our consent. Nobody meaningfully can say “no” if surveillance cameras are gathering that. This is not a problem of people willingly giving up their biometrics. Most of the time, people don't know, which is why a knowledge and consent requirement before biometrics are captured is very critical.
