I guess there are some people who want to be locked tightly in an ecosystem which will be a lifelong dependency for them. Meanwhile Google extracts thousands and thousands of dollars from the "user" over their lifetime.

Oh I get why they do this now...

Imagine if you were a Yurok person and your people lived for thousands of years, as a unique culture, and where substituting off of salmon was integral to that culture, only to have foreign invaders remove you from your lands, put you on reservations, and effectively destroy the lifeblood of your people by damming the rivers. Now imagine how after several generations this would damage your people as a group economically.

Given that history, it seems strange to question that the Yurok people might have financial "benefits" from this kind of project.

I think it's important to note the limitations of these kinds of scales for tracking body fat percentage. From what I remember reading, the technique they use is a measuring of electrical current though the body and then it calculates body fat percentage based on the resistance it detects.

The problem I've read about is that these scales tend to only send electricity the legs and not the entire body, which does not give a great reading on many body types. (I'm not an expert, so please correct me if I'm wrong here)

I think I've seen some other devices that incorporate electrodes on the hands in addition to the feet for a more accurate read. Would be great to see this kind of device added to the project if not already done.

I have always been more interested in measuring body fat % than body weight personally, as there is nothing more depressing to me than standing on a scale befuddled by my random weight fluctuations :).
