To be clear, nobody, but nobody, is a bigger right-to-repair advocate than I am. And I walk the talk. I've shipped hardware whose user manual, at my insistence, included schematics.
But the last time I upgraded the RAM in a PC to keep from having to buy a new one was in the late 1990s, if I remember correctly.
The last time I upgraded the RAM in a portable device -- even a laptop PC, much less a phone -- to keep from having to buy a new one? That would be never... and I'd definitely remember that.
Forcing literally billions of users to pay more because a microscopic minority might want to upgrade their RAM is terrible business, and, frankly, terrible engineering. It's never going to happen again; the ship has sailed. Sorry.
