It certainly demonstrates haw someone, anyone, can track you simply by
looking at your phone. Bear in mind, all of that is discoverable by
Trump's FBI.
I am piggy backed on my wife's cell phone service. She has unlimited
data. I don't because I don't use it that much. A couple of months ago
I turned on the "Location" services on my phone. The data usage pegged
for that month and I was getting "running out of data soon" messages
every two weeks. Turned the location service off and the data usage for
this month is 0.01 Gb.
Obviously, using the location service uses a lot of data. I don't need
a message on my phone telling me the supermarket parking lot is a great
place to take a picture.
