Having a good factual model of a person would be necessary, and perhaps sufficient, for making that judgment favourably. When moving beyond making people more equal and free in their means, the model should be significantly better than their self-model. After that, the analyst would probably value the thus observed people caring about self-determination in the territory (so no deceiving them to think they're self-determining), and act accordingly.

If people declare that analysing people well enough to know their moral values is itself being a busybody, it becomes harder. First I would note that using the internet without unusual data protection already means a (possibly begrudging) acceptance of such busybodies, up to a point. But in a more inconvenient world, consent or prevention of acute danger are as far as I would be willing to go in just a comment.
