People like Richard Stallman have been warning about this sort of thing for decades. Any GNU/GNU, GNU/Linux, or GNU/anything system could do exactly the same thing without violating any terms of the GPL. Requiring a reboot into a special "I know I'm messing with the system" mode in order to mess with important core binaries is not an unreasonable way protect the user from malware, and does not in any way abridge any of the core freedoms Stallman promotes. (and yes, you literally can run a command and reboot your Mac to be able to make changes to the protected stuff, and the process to do this is well-documented)
