I see that coming within case 2. The Intel CPU microcode I gave as an
example has this problem, IIUC. Perhaps I'm wrong, but I see it as
being like the Content Scramble System (CSS), AACS, etc, and we're
waiting for someone to create the equivalent of DeCSS, etc, so that
libre (or at least open source) alternative microcode can be made to
exist that would actually work on the CPU.
In the case of CSS and AACS, software DVD/Blu-Ray/etc players were
targeted rather than hardware ones. Unfortunately, with Intel
microcode, we only have a hardware "player' of microcode: the Intel
CPU, so it is more difficult for the community to solve the problem.
