User-replaceable batteries will require additional space on your phone's body. I'm not willing to trade convenience for a rare battery replacement case.

If you want - you can buy modular phones, pay for that, don't force other people

And I'll go and pay a couple dozen bucks for this work, like all normal people. But eco-activists are starting to say that eWaste is caused by non-replaceable batteries, not by the obsolescence of devices. No one will change the battery in an outdated device, even if it is replaceable.
