you click the box to turn off secure boot

  ...and then some essential software you need to run detects that and refuses to run. See where the problem is here?

    It does no such thing if you enrol your own keys using the extremely well documented process to do that.

      It's fair to think of secure boot in only the PC context but the model very much extends to phones. It seems ridiculous to me that to use a coupon for a big mac I have to compromise on what features my phone can run (either by turning on secure boot and limiting myself to stock os or limiting myself to the features and pricing of the 1 or 2 phones that allow re-locking).

        And the PC situation is only a leftover due to historical circumstances that will be "corrected" in due time. Microsoft already tried this once with their ARM devices.

      Where is this "extremely well documented process" to enroll new signing keys on an embedded device? I don't see one for any of these embedded processors with secure boot. https://pip-assets.raspberrypi.com/categories/1214-rp2350/documents/RP-008373-DS-2-rp2350-datasheet.pdf?disposition=inline https://pip-assets.raspberrypi.com/categories/1214-rp2350/do... https://documentation.espressif.com/esp32_technical_reference_manual_en.pdf https://documentation.espressif.com/esp32_technical_referenc... https://docs.amd.com/v/u/en-US/ug1085-zynq-ultrascale-trm https://docs.amd.com/v/u/en-US/ug1085-zynq-ultrascale-trm

  And how do you do that on some locked down embedded device? Say, a thermostat for instance.
