The article barely touches on it but the real threat isn't from the manufacturers producing newer and better processors, but rather from insurers/single payers not covering the cost of new processors. I deliberately use the word "threat" to answer the question that several other comments ask, or rather point out it's the wrong one: "Why does the processor need to be replaced with a newer model?" In ideal circumstances, it doesn't. But if the insurer/single payer has declared they will not pay for a new one for some ridiculous amount of time like 10 or 15 years after the previous are bought, then the user is under the constant threat that the old ones will break but not be replaceable.[0] That is only tangentially related to old models being replaced with new ones, although this may be the excuse that insurers/single payers use not to replace lost or broken processors, e.g. by insisting that the old ones be repaired even though that's no longer an option (granted, this example would be a combined problem with the payers and the manufacturers). Apparently the upgrade threat is such an issue that the way even exceptional insurance avoids the issue (per my family's experience) is to purchase the user an extra processor at the same time as the processor is first purchased (or, eventually, upgraded): a preemptive replacement/backup unit. This way presumably the payer doesn't have to have on the books a difficult-to-quantify liability from needing to replace a lost/damaged processor with an unknown future model. [0] Critical context: Unlike a hearing aid, the process of getting a cochlear implant physically destroys any residual hearing the user may have had. When the processor is not present and functioning, the user is completely deaf. And that's little-d deaf, which is the problem: cochlear implant users have explicitly chosen not to enter the big-D Deaf world (which largely rejects implants anyways), and so are completely dependent upon their devices functioning correctly.
