The fact remains, you have no clue what they do with that information, how long they keep it, and how many other people have done so. You can't review the code that collects the data, sends the data, processes the data, purges the data. You can't predict how the data will be combined with other data, and you can't control whether or not they share it with third parties, law enforcement, or intelligence agencies. You can clear your history and hope they abide by their word and comply with relevant laws, but fundamentally you don't know. In essence, you have no clue what you are getting yourself into. Because traffic, or something. Society-scale, this is a serious issue, especially when the default is "on". Opt out!
