If the issue were the brakes not engaging, sure, I'd blame Tesla. When the issue is "the parking brake may not disengage and then you'll have to call AAA and your ice cream will melt," I'm okay with blaming the supplier.
Granted, from what I understand Tesla paid for everything and fixed his car; it's only his time that was spent on this, but every car breaks down at some point too.
Oh, and they were able to eventually move his car by elevating it onto a set of rolling beds, and then rolling it onto a truck that way. It looked pretty funny :)
