You should probably do do some reading on the subject to gain a bit more understanding:

> This puts [Apple Silicon Macs] somewhere between x86 PCs and a libre-first system like the Talos II in terms of freedom to replace firmware and boot components; while a number of blobs are required in order to boot the system, none of those have the ability to take over the OS or compromise it post-boot (unlike, say, Intel ME and AMD PSP on recent systems, or the DMA-capable chips on the LPC bus running opaque blobs that exist on even old ThinkPads).

The Secure Enclave is equivalent to a PC's TPM (a TPM is now required to run Windows) not any form of a management engine.

AMD PSP is little more than an embedded TPM. The capabilities are significantly different vs. Intel ME.

Again, you've got some reading to do.

> the subsystem is "responsible for creating, monitoring and maintaining the security environment" and "its functions include managing the boot process, initializing various security related mechanisms, and monitoring the system for any type of activity or events and implementing an appropriate response".

Critics worry it can be used as a backdoor and is a security concern.
