As the hardware iShittification continued, macOS too was also being slowly stripped of features to ensure Apple controlled your data and what you could run on it. Support for independent Kernel extension (outside of Apple's control) was removed mainly to cripple existing independent Application Firewall and virtualisation software. Apple-made OS APIs for these were integrated to the newer macOS and offered as replacement to ensure Apple controlled how Application Firewalls and Virtualisations should / would work on macOS. (Such restriction on the kernel extensions for independent system developers is also meant to prevent support for other filesystem, like ZFS for example - the OpenZFS project is maturing fast on Linux, Windows and macOS and can be a game changer as its usage has the potential to "free" our data from a closed and controlling ecosystem, to be used on any platform of our choice.
Whether you are a developer or a user, a "consumer relationship" with Apple feels like a relationship with a controlling and abusive spouse who repeatedly gaslights you that you are imagining things and are the one at fault because "you just don't understand them".
