I think there is: It is the line between "not spending extra money to make sure it works" and "spending extra money to make sure it won't work".

There is a related problem with warranty: an inferior third-party replacement part may cause damage to higher-quality original parts. There is a line here between "making sure you don't have to deal with follow-up damage caused by inferior parts" and "preventing the use of inferior parts". This is a bit more blurry because most cases won't be clear-cut, and dealing with them will be a burden on the original manufacturer.

I think it is important that we reward the nice players as much as we punish the bad ones. A blanket "all companies bad" just means that no company has an incentive to be anything less than bad.
