As of 2022, 40 million units had been sold, so after 16 million they'd need the first change, after 32 million the next, and so on. With WiFi needing more addresses and Pico-W using more too, they need a lot more prefixes if they want to avoid re-issuing the same addresses. | |

UK laws govern finances of charities, and of course charities are not permitted to make a "profit". Here's a thumbnail sketch of their finances. It seems a reasonable guess that money is behind the decision, more specically how it is accounted for and distributed. | |
