linux and voila, you got your freedom back
Apple silicon Macs have the main CPU cores fully in control, with zero external peripherals having full DMA access to system RAM (everything goes through IOMMU), and have an interesting secureboot architecture that allows different security levels on different OS installations (you can run unsecured Linux side-by-side with a fully Netflix-ready macOS).
I have much worse news about the typical Intel BootGuard'ed PC laptop.
