From an individual's perspective, a great deal of their personal / private data is accessible to other entities, whether governmental or private. That ship has largely sailed. However, not every piece of data is accessible to every entity, and it can be worthwhile to prevent entity A from having my location data even if entity B already has it. I do find it interesting, however, that some people perceive the greater threat to come from private entities rather than government. Historically, and in terms of our legal framework, most privacy protections are designed to protect us from government, because government had extraordinary power. Now, some perceive private companies (particularly tech companies) to have arguably MORE power than government, in part because of what machine learning algorithms have been able to do with data and how the use of that data can impact us. And even anonymous location data isn't really anonymous. https://www.nytimes.com/interactive/2018/12/10/business/location-data-privacy-apps.html Source: https://www.chevybolt.org/threads/remove-mobile-data-chip.33237/post-876038
