This is a related issue but not the same.
The previous discussion was about how Big Sur has some built-in exceptions for Apple software.
The current discussion is about the discovery that these built-in exceptions can also be abused by non-Apple software, rendering the firewall completely ineffective.

Many of us considered this to be a forgone conclusion. But it's nice to have a proof in hand to convince the overly credulous.
