Someone send Apple an early model smartphone from the 2000s.
They have a removable back and you can swap batteries in and out in seconds.
The system was on windows smartphones, android smartphone's. Even laptops had removable batteries. Even Apple devices 🙄🥴
And all those came with tradeoffs of their own, namely structural integrity, plus batteries had to be smaller.
At the end of the day, it all comes down to individual rights vs collective rights.
Yes, Apple could make every phone modular and repairable, but if only a very small percentage of users actually wind up making use of that opportunity, this just means that the rest of their user base is basically paying extra and taking on all the drawbacks of all the additional tooling, supply chain etc needed to enable this. It's like saying that maybe 1% of smartphone users will actually need removable batteries, which means that 99% of users have to deal with the downsides of smaller batteries (and consequently, less battery life), vs simply putting a bigger battery inside the device and calling it a day.
Even if I belonged to that small group of users who may want such a feature, I would take a good look around me, and decide that it's simply not worth it for the cost of a global increase in cost, energy use, pollution and so on. Yes, I am disadvantaging myself, and that's what it means to live in a society where I do not view myself as the centre of the universe. Not everything is about me.
Apple's position right now seems to be to remove as many moving parts from their devices as possible, thus minimising the number of things that can go wrong with them and drive that repair need to as close to zero as possible. It has been their focus for well over a decade, and it also means that it may not be worth worth it to support global repair efforts on a societal level.
It's also no surprise that the criticism Apple has received comes mainly from people whose financial and ideological goals are at odds with that of Apple's (namely iFixit and Louis Rossmann). It does mean the latter is wrong, but I also kinda see why Apple is trying to go with all of this, and I am not really opposed to it.
This is also why I have always had issues with the whole "You don't have to use X feature if you don't need it" argument, because it assumes that every new feature does not have its share of tradeoffs and opportunity costs. It's the case for expandable storage, it's the case for third party app stores, it's the case for running macOS on the iPad. Engineering simply does not work the way you think it does.
Like I said at the start - individual vs the collective.
