I don't think yours is a serious answer, what I said already refutes your points. Ubuntu has already made me waste a week and I don't want to waste any more, particularly when you can't or won't listen to what I say and look for irrelevant excuses like the availability of UEFI vendor updates. Just FYI Intel provides these updates for very good reasons and RHEL/CentOS/Fedora have been providing processor microcode updates for ages now and with relatively frequent updates (see the microcode_ctl RPM changelog). Bye now.
