> You wouldn't want someone removing a battery from one device to try and retrofit into another and then sell the refurbished device as safe.

I feel like you've never had your car repaired before...

This is exactly something we're fine with protecting and encouraging. The manufacturer of the defective part is at fault, and depending on circumstances the repair person, not the company who originally built the device. Go ahead and try to get Chevy to sell you a brake master cylinder for a 1970 C10, your only options are after market parts manufacturers and that's fine, we've dealt with this for literally as long as there has been n > 1 blacksmiths in a town.
