It was about the radio and being able to modify the radio firmware.
As many modifications would void the FCC certifications of the device, due to changed parameters (more power, disabled anti-interface mitigations, out-of-band channels, etc.).
This was avoided by making the radio firmware separate blobs, but there was a real danger of the whole device having to have signed firmware.
