I'm also not a fan of Windows 10 precisely because it updates itself.
The truth is that the big American tech companies are showing off with their statements on this matter. First Intel puts its marketing team to work to give a ridiculous and shameful explanation for the failure (nothing less than saying that it is actually a software failure) and now Microsoft is dodging the issue with AMD whose micros, by the way, do not have speculative memory prediction and are therefore free of guilt.
Without being a fan of AMD (or Intel or any) I have to say that they are treating the company shamefully in this matter: in Linux the patch is applied to their processors by default (I don't know if in the last hours it has changed) harming the performance in the appropriate tasks (it does affect virtualization). And now they are defenestrating an entire platform, because in the end the user sees that their PC doesn't work, not because they use Windows, but because they use AMD while the one next to them who uses Intel, does work.
