The 386 and 486 patent should have expired more than 20 years ago. No one tried to open source it. https://github.com/EI2030/Low-power-E-Paper-OS/blob/master/0... There were many companies that had clones in the early 90s, and I wonder whether any of them still have the rights to manufacture them.
" That is a better reason than elegance. and I want to tell Mr Grinberg, that the word priviledge he tosses around in his article also extends beyond the ISA depending on where you are in the world."
Grinberg is an emigre from Ukraine, which isn't the most privileged place in the world. In fact his research articles go deeper than the average software developer in Silicon Valley.
There are 386 and 486 open source reimplementations in Verilog (see z386 and z486). As far as I know, existing commercial 386/486 chips still manufactured (yes they exist!) are descendants of Cyrix work, not Intel or AMD. Consequently, VIA may be contractually holding those back rather than Intel/AMD doing anything there.
