> Microsoft strong-armed processor companies to not support Windows 8 and instead force Windows 10’upgrades if you wanted new machines

Do you mean to say that Microsoft clearly communicated Win8 EOL dates and OEMs choose to move accordingly? If not, can you cite a source?

Edit: after some googling, I think you mean - Microsoft didn't think it was worth the expense to pay engineers to backport processor support to Win8. Bit of a difference from "strong-arming" the processor companies
