Summary: The Linux Foundation helps undermine real security by letting truly untrustworthy companies lock systems down (via OCP, a Microsoft front group which pretends to be vendor-neutral), just like it did for IBM with TPM/2
Ignore the scapegoat, focus on who is a proponent for imperial back doors. The Linux Foundation is fronting for them.
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.
