When I give a dress shirt to a professional dry cleaner, I'm not personally responsible for it while they're cleaning it. Its still my shirt. I'd consider using a different dry cleaner if they started keeping notes on what they thought I did to make my shirt dirty. If they lost the shirt, I'm angry and may even get some compensation, but the shirt is still gone and someone else probably has it.

I completely understand that the scale and scope of abuse in tech can be much higher than with other services due to automation, but I don't see how its reasonable to question whether my stuff is still my stuff because I've entrusted it to a third party.
