Devil’s advocate: you’re free to run whatever you want on the device you bought, but some of the software you licensed prohibits you from running your software on top of it.

Also, actually running your software may be a challenge because the boot loader and OS are locked down, but you could have known that when you bought the device.

(This is similar to “right to repair”. That isn’t about being allowed to repair your devices, but about making it easier to do so. You’re free to repair your device, but it currently often is almost impossible)
