1-99.99999999% of people on earth is 0.8 of a person. Forgive me if I don't buy into your thesis. Seeing as the vast majority of people don't even understand the implications and extent of always-on pervasive ubiquitous tracking and surveillance, an honest metric would be: what percentage of tech-literate people don't want to be forced to have wifi-tracking enabled to access a feature which doesn't need wifi-tracking. As you can see from this forum, that percentage is quite high.
