If you gave a scrolling wall of terminal text to the average PC user and then asked "yes or no", they will just say "yes". The point of Linus's video was "is Linux ready for mainstream", so his actions were fair imo. Linux users forget how simple using a PC is (or at least was) on Windows and Mac.
You would get the same result on any operating system by disregarding a warning like that.
When does Windows or MacOS allow you to purge your desktop environment? They would simply not install the software. They wouldn't give you the option to break your PC in the first place
