The fact you can run old software on any PC still is a pretty tremendous feature. Apple kicked of 32 bit apps from Mac and iPhones, its user accept that, business PC users might not. I have a number of IOS games I enjoyed that are no longer usable (yeah I could have stopped upgrading my i device, but the security problems make that not a viable option)
Conventional wisdom in the mid 90s was powerpc (RISC) would eventually be better the x86, but it never happened. They worked around the issues. And Microsoft eventually made an OS that wasn't a crash fest (I'm looking at you windows ME)
Also no one can afford to be on TSMCs best node when Apple buys all the production. Apple's been exclusive on the best node for at least a couple years now. Even AMD isn't using TSMCs best node yet.

Yeah, but that was (at least on the Mac) not a technical requirement, they just didn't want to carry around the kernel-side support any more. IIRC it didn't take long until WINE/Crossover figured out a workaround to run old 32-bit Windows apps on modern Macs.

Samsung has their own competitive fab process, but they still have yield issues [1]. It's not like TSMC has a monopoly by default.
