Caveat: This reply got a longer than intended and broadens a bit, but please indulge me because I think you are also onto something I have been scratching my head about for decades now, amidst outrage for questioning tech dogma.
I agree with you to an overwhelming degree. I also had an iPhone 6S until about a year ago and I have to say the upgrade to the iNext Pro was pretty underwhelming in many, if not most ways when objectively evaluated.
I have also had AirPods for however long they have been out and even though I would agree with the rebuttal to your point that many other BT headphones are notably even more glitchy, I also paid about 5 times less for some of them that work almost just as well in most ways and aspects.
There seems to be an odd kind of self-delusion going on where somehow whatever is new, is assumed to not only also be better, but significantly better, when if one just takes a first principles approach to evaluating that proposition, at best you find marginal or incremental improvement of diminishing returns.
The 6S was released over 6 years ago, is it even doubly as good, let alone exponentially more capable? There is a huge hurdle in overcoming the reality that the answer is no.
There is all this lamenting about sustainability and environment this and climate change that, but for some reason, e.g., an old Apple device (picking on them because I believe they are the highest standard bar) cannot perform as well due to simple UI and UX changes?
There is seriously something wrong with the whole matrix and I have not been able to get any kind of satisfactory answer as to why, e.g., an old 1st (or 2nd) gen iPad Air all the sudden cannot perform †h same simple, core tasks it performed exceedingly well when it was new, that being loading safari and less than demanding website like HN.
What has changed in the 9 years since the 1st gen iPad Air came out that all the sudden browsing is now an extremely demanding task on the device? It seems like intentional and fraudulent designed obsolescence. Where are the environmentally concerned drawing attention to this like I am?
Just imagine if your car got updates every year, and then you find that 9 years later all the sudden the same engine has 100 less horsepower and can't get up a moderately sized hill anymore. That's not suspect to anyone else?
Again, I would love for someone to explain how I am wrong, that I cannot expect a product I buy to retain the same performance for the same actions/tasks when nothing else has changed. Does the CPU age and die off?
We should all be demanding that a device must retain its performance in all aspects of the original function. Everything else is fraud. Please for anyone compelled to, refrain from your "you don't know how it works" comments, that is not the case, nor helpful, and rather blind to reality.
