Privacy as its own axis is the part the free location tools quietly drop, since the free tiers are paid for by exactly the parties you would want excluded from the ranking. The variable that is hard to model is that most of the exposure is not legal but commercial: what a country allows on paper and what its data brokers actually buy move independently, and the second one is decided by daily habits more than by jurisdiction. Does unwatched score legal surveillance - camera density, retention rules - or commercial data flow? Both are worth having, but they should not be mixed into one score.
