Does it bother you that you're being tracked?
On the one hand, I opt-in to location tracking for apps and services such as Google services, because I genuinely believe that I benefit greatly from location-targeted information. On the other hand, I would opt out of any other location tracking of my cellphone to companies that I do not see the benefit of having. I want fraud-protection and no liability when it comes to fraudulent purchases (opt-in for credit card companies and banks), but I don't want the government/Facebook/retailers/insurers to have this access without permission.
No, it doesn't really bother me. Why would anyone care that I get up around 7AM on weekdays, drive to work around 9, stay there until 5, and then drive home?
On weekends they will see me going to Target and the grocery store. Sometimes another store. Sometimes I go to visit my family in another city.
I really don't care if people have that information. Many people (not me) post that information freely on Facebook, Instagram, or Twitter.
There are some future situations in which I might care that I am being tracked. If that were the case, it's highly unlikely I would bring a phone with me.
Would I prefer not to be tracked? Probably. Does it bother me that I am being tracked? Nope.
I suspect these views line up with the majority of people in the US.

Just because you have no self-esteem doesn't mean other important people shouldn't have rights.
Edit: While things are "good", I'm sure you and a lot of others don't see an issue. But you're giving yourself a lot of rope to be hung on if ever things become hard.
Nobody before that point really stopped to consider whether or not it was a good idea this data existed in the hands of the people that had it. If they did, they probably thought there was nothing to hide (or even that it was a good idea, perhaps). At this point, we should know better. For the ones targeted, there were no bigger problems than the fact that someone had this data about them.
The problem is that, today, you can't predict what will get you in trouble tomorrow. So even if you intend to live your entire life in complete compliance with whatever the current government wants, you won't be able to live in compliance with what the next set wants in the future. You can't simulate liberty by keeping your head down - eventually you will disagree with the government.
To a lot of people, "disagreeing with the government" means convincing a population that is largely happy with the way things are that something unjust or wrong is happening. That's the pattern of civil rights, environmentalism, and other activist movements that we have had in the West. This is not the whole story: in countries and times with poorer situations, disagreeing with the government can mean a conflict with your own practical (economic) well-being, as a member of no particular minority. In fact it is all of this bean counting about rights an liberty that keeps us away from "disagreeing with the government" in ways that are easier to convince people about the significance of.
