If you work at some retail electronics hellscape long enough I'm sure even Mother Teresa would eventually give in to the temptation to supplement her income by selling customer data, or at least alleviate boredom by browsing pics. I guess I trust apple's file vault enough that I'll allow them to repair a laptop without a password. I've had two apple laptops fixed and to their credit they didn't even ask for the password.

I would never give a repair place a password though. It is better to just buy a new device.
