I asked a friend about why their company could not keep their devices up to date for more than two or three years. Basically, they did not have long-term maintenance agreements in place for the underlying subcomponents. The subcomponents were filled with vendor coded firmware blobs. There was some desire to fix this going forward for marketing purposes, but little desire to go back in time to fix old devices that were short on support.
