Really . . .
Various forms of this has been going on in the electronics industry since I remember when getting in around 1993. In those days it was new computer gear released 6 months after you bought yours that was twice as fast and two-thirds the cost. Consumer outrage ensued!!! Lawsuits were rampant, as were the accusations.
Then it was updates of OS's that sucked machine performance that required more ultra-expensive memory that some couldn't (or couldn't afford to) install, or sucked up the puny hard drive space. Follow that with Apple's insistence of changing from '040 to PPC to Intel, and today, to M1. That can sideline perfectly good hardware in a short period of time due to dwindling updates to software for the old system.
While I have lived through it, I can't say I like it, but that's the reality of the electronics world. I applaud the Briggs & Stratton business model, and I know of a few like that in my world outside of digital 'stuff', but I can hardly expect a 1998 Apple G3 Wallstreet to be fully functional, AND serviceable, in today's world. I think this Apple battery thing is really overblown by a lot of folks who haven't yet faced the reality of the electronics world. And I might add, Apple isn't alone in this battery thing.
Would I like to be able to field-strip my MacBook Air (which is pretty easy already) and add in a new M1 chip to continue. You bet I would! Do I think for a second Apple is going to be a stand-up firm and accommodate me? Nope.
