Well, if someone holds the information, among other things, governments will make laws to be able to get at said information. Or they just send intelligence agencies in to go after it in the first place. If you've ever seen any presentations or news articles about/by Ed Snowden for instance, you'll know to what lengths even a solid democratic government like the USA might go to. And, you're right. Though previously tracking has only ever caused death/injury/severe_national_embarrassment when the data has been obtained by governments, censuses, counties, post offices, phone companies, and possibly social media companies that start with F; so far social media companies that start with Z have not caused any problems that have been reported in the news where I live. We should therefore trust social media companies that start with Z, because they have a flawless track record.
