Isn't that Apple's argument for not allowing you to get your battery replaced by a 3rd party, because customers might buy a cheap off brand battery and it could cause their phone to catch fire?
Yes. The difference is that, unlike possible phone fires, we know franchises will cause listeria outbreaks if left to their own devices because they have done so. It was a whole thing in the 90s and the obvious reason why McD's implemented the current policy in the first place.
