"We will no longer support this even though me promised ten more years. Here's a $10 credit to your account, which is more than we have to do because of our TOS, and it's more than you should expect because of the binding arbitration clause."
Making them say how long something will be supported means nothing without controls on TOSes. It's just a way to push the responsibility onto consumers.
Forcing companies to make things work even without on Internet connection seems like a good step, though implications for DRM and video games are interesting.
