This will make various compact designs difficult/impossible (such as airpods or other small wireless earbuds).
This will make waterproofing difficult/impossible/lower quality for many device classes (phones, earbuds, etc). Waterproofing on these devices requires adhesive (not easily replaceable) or ultrasonic welding (not user serviceable at all).
For a while companies like Motorola were selling nano-repellent (essentially hydrophobic) coating phones and calling them splash proof. You could easily design a gasket or something, existing waterproof phones already have parts that open for eg the sim card or microsd slot (which are gasketed).
If they don't want to, then they can make something less rugged.
No excuses for resource waste and pollution.
Making sure something survives splashes or a minute at the bottom of the swimming pool will be enough to keep most of these things working.
If a company asked me do I want 50% more battery life or 1mm thinner, I'm going for the battery. And lots of people would. How many people moan about their battery, and how many say "ooo, I with this phone was just a hair thinner"?
But you don't get a choice, because it's all bundled up with other features to make it for you. Want NFC? Ok, you have to have the flagship model with the thinner case.
Oh, you want the bigger battery, sorry we don't actually do one because we only had one model called the FailChungus 0.1 with a big battery and no one bought it (never mind that it came only in brown and had a 480x480 screen).
Same for the 3.5mm jacks: no one has ever gone out and deliberately bought a phone without them. You just don't get a choice if you want everything else. I specifically got a non-flagship phone to keep that port, but I missed out on a lot of other stuff.
While it's nice to think that consumers lead these choices, I don't think that's actually what's happening: the illusion of choice is given but the companies gradually do what they wanted to do anyway.
I think it can not be denied that the current smartphone business has a negative ecological impact (waste during the whole life cycle except during usage) and additionally also a negative social impact (manufacturing conditions as well as rare material extraction; not sure if broken phones are shipped to Africa like other e-trash, but would expect that as well). These long-term impacts are not in our interest, but no individual alone can change that in the current market. But that's often the case: If we are not strong enough alone, we work together and bundle our power. Like in a state or even above the state level.
Choosing between a battery-farm chicken and a free-range chicken has one variable - the provenance. But then let's say you like KFC for their 'secret' spice blend. But KFC don't care for offering free-range chicken. If you want that spicy chicken: you can sacrifice your preference for free-range chicken, get spicy chicken from somewhere else (not what you wanted), or go without.
Smart devices have many more variables. So the likelihood of something you want not being there is much greater.
And once a feature has been removed from such products, it partly becomes self-fulfilling.
Living has a negative ecological impact.
How do you measure that? People seem to get more benefit out of the phones than their cost.
Phones aren't cheaper now than when they've had user replaceable batteries:
Galaxy S5 (2014): $650 ($780 in 2022)
Galaxy S22 (2022): $800
