Summary: Techrights did not forget how UEFI 'secure' boot came into kernel space (see the below); This proposal came from Red Hat and then foisted/pushed onto Linus Torvalds by at least 3 Red Hat employees (the mainstream media blasted Torvalds for his response to this 'offensive' technical move by Red Hat, helping Intel and Microsoft control silicon at CA level)
At this point it would be rather foolish to assume that IBM will let Red Hat just "do its own thing" or maintain its corporate culture, identity, projects etc.
