More fixable is good
Back when there was such a thing as manufacturing in the UK many decades ago, I did a degree in Manufacturing Engineering. One of the courses even back then focused on making kit easier to strip down to access or recycle. With the quality of engineers Apple can employ, I was upset at all these solid blocks of glue they'd make, increasing to waste, and so am actually pleased they've taken a fresh look at this.
It's not going to cost them sales (the point of being a fashion brand over utility brand), and is hopefully just going to mean less pollution when the handsets are crushed and burned for minerals on some Asian backstreet in a decade.
