> Macs were quite repairable and most parts were replaceable until ~2012. So it’s hard to blame Jobs for that

Not "blaming" because I'm not convinced it's the wrong move. Soldering memory directly onto the logic board has advantages relative to a fully-encapsulated drive.

Apple learned this, in part, from designing the iPhone. And Jobs always had this penchant for pushing design to its limits even when it sacrifices conventional (and in some cases, probably necessary) functional requirements.

What I am convinced about is the lunacy of the planned-obsolescence argument. The longevity of Apple's products simply doesn't support it.
