That doesn't stop the background tracking
Background app refresh never stops the app from running.
Just found how they pulled a Facebook on this one
"The profile covers a variety of different things about Uber and is well worth a read, but the most startling tidbit of information is just how far Uber went in trying to trick Apple engineers. What Uber wanted to do was assign a persistent identity to iPhones with a small piece of code, better referred to as “fingerprinting.” This tactic, however, is in complete violation of Apple’s rules as the company believes a device should offer no trace of the owner’s identify after being erased.
Here’s how Uber maneuvered around these rules:
So Mr. Kalanick told his engineers to “geofence” Apple’s headquarters in Cupertino, Calif., a way to digitally identify people reviewing Uber’s software in a specific location. Uber would then obfuscate its code from people within that geofenced area, essentially drawing a digital lasso around those it wanted to keep in the dark. Apple employees at its headquarters were unable to see Uber’s fingerprinting."
Well I was wrong at least in Uber. Talk about coincidence, Tim Cook threatened Uber CEO to remove the app from the store

But Facebook still got away with it
