Objective Development have made an interesting blog post regarding Apple's Network Extension Framework in macOS Big Sur.

When we first discovered that Apple’s new Network Extension Framework — that all third party firewalls are now required to use on macOS Big Sur — didn’t report network traffic during some large software update download, we reported this bug to Apple on July 1 (FB7839544), hoping it would be fixed in the final version of Big Sur.

But it came worse. Three months later we realized, that a number of other Apple services like App Store, Maps or FaceTime also showed this strange behavior of acting invisibly, bypassing the new filter API. So we reported our new findings again on October 1 (FB8762834).

As it turned out, this behavior is on purpose…
