There's no dispute that the modem is the NTE and that it belongs to Openreach.
Surely you have therefore answered your own question. Isn't the answer to that obvious?
If you hired a car would you doubt that you were not allowed to alter the setup of the ECU?
If someone lends you a book, would you happily write margin notes in it?
It doesn't belong to you. You agree that. So that's the end of the matter.
Some of us load a hacked version of the firmware onto it. That is probably prohibited, but we can easily restore the original if challenged.
Others don't use it, and obtain their own VDSL2 routers. With varying degress of success, I might add! VDSL2 implementations seem to be far from standardised. Again, if challenged they can reattach the OR modem.
