They also claim the AoA Disagree alarm was included as an optional extra "inadvertantly".

Incorrect! That's not what the BBC says, nor the NYT, nor Boeing:
When Boeing began delivering its 737 Max to customers in 2017, the company believed that a key cockpit warning light was a standard feature in all of the new jets.But months after the planes were flying, company engineers realized that the warning light worked only on planes whose customers had bought a different, optional indicator.In essence, that meant a safety feature that Boeing thought was standard was actually a premium add-on.
