I am aware, but the cell network itself is considered critical infrastructure as well, and operators are custodians of the radio spectrum. So devices that don't respect operator settings are considered problematic.

Now, do operators abuse this power to enforce commercial interests? Absolutely. This may well be a case of that. But the general principle that devices that operate on the radio spectrum and in cell networks are bound by laws that constrain user's rights, and that manufacturers are responsible for enforcing said constraints in their devices for the good of everyone, is not invalidated by a few greedy policies. Just legislate against the abuses, as the EU for example has often done in this area (leading to free roaming within the EU, legally mandated ability to move to a new network keeping your old number, etc).
