They already have the ability to prevent alternative operating systems. They use the same or similar SoCs in their other product lines and those do not let you do this.

Yes, Apple put effort into making it possible to install alternative operating systems on Macs, but that is an exception to the design because the chips are designed to be locked down. I expect Apple to remove the option at some point because nobody is using it on any of the recent hardware.
