> the phone call he is making with someone else's phone is not depriving him of his freedom/privacy, but its owner's.

Maybe he's not being hypocritical, but that position -- I will pragmatically use others' phones for my convenience, but I will not retain one myself -- just seems shitty. Not sure why, maybe because it's even less of a universally applicable tenet than "phones are bad, mmkay," it's just "I'll use the systems as convenient for me, no matter how others may suffer under them."
