Cell phone Creators are Clearly Jerks

Getting back to the whole cell phones ringing tangent, I started to think about who designs these. For one, why is there a "Turning off Phone" song that has to play when you shut it off. I shut my phone off so there is no noise, not so I can be harmonized. Two, why when you try to turn the volume on the phone down it beeps so damn loud. Those two reasons alone give me reason to believe phone manufacturers are assholes.
