It was an example.

The (perhaps implicit) requirement is that a device has no unneccessary
limitations that it becomes unusable at a specific expiry date within
a time period where the hardware and software is expected to still be
fully functional.

If a device becomes obsolete because the world has moved into unpredicted
direction the vendor could not forsee, that is acceptable. However, producing
equipment that you know is going to fail on a certain date only three years
into the future is most probably not.
