Looking at implications is a thing I do a lot.
You know how it is common practice in some areas that if you return a defective product you either get a used one as replacement or even if you get a new one the original warranty period continues and is not reset?
This is common, yes, but it is also bad style. What the manufacturer is basically saying is this:
You are not buying a product. You are signing an open-ended usage contract with a minimum guaranteed length. We don’t think our product should be of proper quality and last at least x years, but that you are buying x years of product use. If we keep selling you crap, it is your problem that will haunt you to and beyond the eventual end of the contract. Don’t expect to have a useful product beyond the warranty period.
