Power and money are easily the biggest goals and wants that lots of people have.

But I do (still) trust in the goodness of men.
I'd argue that e.g. an open source system could have a (more) benevolent cause and help someone with these problems without using data (gained) for profit.

No surveillance (or monitoring) and no data gathering means you cannot see how good/bad something (such as a behavior) is. And in such a situation it's difficult to come up with tools to help, if there's "no problem to give help to".
(One can always self-monitor e.g. time spent in an app)
