On the flip side of the loss of privacy: location and similar data can be used as a solid alibi if you are accused incorrectly.
How many people have been silently tagged as innocent because of their data stored?
That said, ersonally I find the loss of privacy abhorrent, especially because I have fuck all rights in the US (not a citizen, so the US government and US corporations can abuse my personal information with very little recourse from me or my own government).
