sorry, read what you sign lady.
It has been greatly exacerbated by people who are unwilling to read a twenty page document to obtain a few minutes of convenience on the Internet.
People sign stuff all the time they don’t read. Even me. When I install software on my phone or computer, I rarely read the text of the EULA that you sign by clicking the checkbox which says “I agree to the terms of use...”
That is how a huge amount of surveillance and tracking information is given away nowadays. We agree to be monitored on our cell phones. Granted, it is, to a degree, anonymized since they collecting entities may know who the cell phone is (via the MAC address which the applications using location services can and do provide) but someone knows who that MAC address belongs to.
All they have to do to reveal your movements is accept a subpoena to link a MAC address to a name (to a company like Apple which sold the phone) and be willing to buy tracking data with money from a company that warehouses that information.
Of course, I do read a lot of things I sign, but I fully admit to not reading some things like these EULA agreements.
