A lot of us have been conditioned to think you "just can't" modify things like firmware, or OSes, (or increasingly in phones/tablets, user-space). But for Stallman's generation, hardware devices were 100% owned, repairable and hackable by their owners. Only software and the abuse of it could so comprehensively change a hardware device from something you obviously own, to something which in a real sense you don't control or even realistically own anymore. Apple is leading the charge in this as other companies itch to pile in.
Every manufacturer the world over is right now wondering how they can turn their one-time sales into a recurring revenue stream.
Case in point: the Bosch e-bikes now offer a 'Bosch account' to supposedly access premium features on the bikes which in a sane world would be included in the purchase price and which really do not require an online account or service to begin with.
Maybe I'm curmudgeonly, but I'm tired of things I choose being changed on me, things I own be used to profit on me, things I use to spy on me. And its not just software and hardware. For example, I bank at X, but they've merged with another bank and are becoming Y. So now different website, different checks, different name, etc. and for what? for a line on some CEOs resume. Similar when I make a loan and the loan is sold to someone else, and my payment processing routine has to change to accommodate someone else's profit-making deal.
It's more likely the CMOS battery is duff or some other issue
