I still hope that one of these days people in general will realize that executable signing and SecureBoot are specifically designed for controlling what a normal person can run, rather than for anything resembling real security. The premises of either of those "mitigations" make absolutely no sense for personal computers.
Does that mean that Microsoft doesn't also use it as a form of control? Of course not. But conflating "Secure Boot can be used for platform control" with "Secure Boot provides no security" is a non-sequitur.
