Data and dataset
One reason we may be having difficulty with this section is that "data" can be literally anything from basic facts, which is what lay people think of as "data" to professional works of fiction or visual art, which lay people think of as more than mere data. And those lay intuitions are legally relevant.
As a result of these distinctions, and the many other rights issues that may arise with certain types of data - e.g., health information or nude pictures of real people, this area seems like the most ethically complicated.
I don't have a good answer here, I'm just trying to call out why this feels more challenging. Maybe that will help shake some ideas loose as we continue to iterate.
