Let's face it, Apple has no interest whatsoever in designing their products to be repairable. They want their products to look stylish, it is all about design. If the best design means no externally visible screws, extremely compact design, curved white plastic bodies, thinness, that is what they will do. It hasn't hurt their bottom line... and other manufacturers are following suit.
If companies gain market share and profitability BECAUSE they make their devices easier to repair, other companies will do the same. But as we have seen, Apple has proven that nobody cares about repair as people continue to shell out more and more money for crap they probably don't need and only do so because Apple's marketing is so amazingly effective.
Apple has also shown us that they can do things like create their own proprietary connectors, protocols and other standards that will keep Apple users tied in to their ecosystem... and users take it up their arse like champs, gladly shelling out more and more money. I don't know if they plan on adopting USB-C across the board but for now they are profiting nicely from their locked-in systems. I also remember their Bluetooth connectivity was also broken, to the extent that I had no issues connecting certain devices to Android and BlackBerry and almost every other phone, but Apple refused to properly connect to it (like it was using it's own "interpretation" of Bluetooth protocol).
I don't want to pick on Apple only... this is happening across the board to various extents by all companies. The only way to vote is with your money. Refuse to buy anything you can't tear apart easily and repair if needed, or just accept the fact as disposable electronics are now the norm and prepare to pay continuously as batteries continue to die.
I for one am using a Garmin Vivofit 4 which runs on a single battery that you change yearly, not a rechargeable. How many smartwatches out there have now glued in batteries that you charge daily/weekly? How easy is it to change them? My wife's Apple Watch decided to pop open a few weeks ago... battery swelled and screen popped off the case. It was under the "extended" warranty Apple has because there was a major problem with many of their watches. Otherwise, that would have been an expensive needless repair, as it hasn't been that long. Next time the battery swells and decides to pop open the watch (or explode on the wrist) I am not so sure Apple will fix it.
