Well, seeminly obvious answer would be "In-App advertising" or "Brand recognition" or some other bullshit marketing term.
When you download an app, most of them demand certain access to your phone. This includes access to your camera (take pictures), access to the microphone (record sound), access to all your files.
Now tell me, for an app that tells you the temperature in Tahiti - why the fuck would it need the above to function??
Remember the old Thai/Chinese saying
"Mais mee free yu nais Lop" (and fuck right off you phoneticians - that's how it sounds)
