It's obviously more likely it's just fans of the language with a knee-jerk reaction of "ackshully you're totally definetely wrong, but uh... don't ask me how, you just are" than legitimate talking points.

It aint stupid if its the truth lol

Feel free to stay "ignant" though, making stupid claims and refusing to back them up when asked.

alpha, hppa, m68k and sh4

To be fair, lots of people did use Motorola 68xxx CPUs when those were new, it's just that it was 40+ years ago in products like the Commodore Amiga. The SH4 is most popularly connected to the Dreamcast, Sega's video game console from back when Sega made video game consoles.

The Alpha and PA Risc were seen in relatively recent and more conventional hardware, but in much tinier numbers, and when I say relatively I mean early this century, these are not products anybody bought five years ago, and when they were on sale they were niche products for a niche which in practical terms was eaten by Microsoft.
