I looked up the datasheets, and the 'sustainability' argument doesn't hold water mathematically. I'll use the Fairphone 5 to match the same timeline for support as a comparison, because they are targeting the same market within the same hardware timespan. ​Fairphone 5 uses a Qualcomm QCM6490. It's an Industrial IoT chip with a guaranteed 8–10 year support lifecycle from the manufacturer. That is how they offer long-term support without a subscription: they bought the right hardware. ​The Shortfall: Punkt chose the Dimensity 7300, a standard consumer chip released in May 2024. MediaTek typically supports these for 3–4 years. While Punkt sells 5-year subscriptions, the hardware vendor will likely move on long before that subscription ends.
