Fine, poor phrasing from me. I should have said "Apple, and most phone makers, have seen that most phones get replaced in 3-4 years and so they have made the decision to glue their batteries in place to get extra capacity" - Apple is a mass market device, there is little upside to them designing for the small niche of people who want to run their phone into the ground and not upgrade.

Little upside until that “small niche” started reverse engineering the behavior of software that Apple designed explicitly to address this segment of their paying customers.
