Based on the article it seems this is a safety feature to prevent the accidental activation of those functions in flight.
I imagine there’s zero reasons for using ground spoilers or reverse thrusters in the air, and doing so would probably cause a complete loss of aircraft.
So to make sure that can’t happen, the functions require a positive “it’s safe to active now” signal from the flight computers.
So the functions themselves are quite capable of operating without the flight computers. They simply refuse to do so unless a flight computer has given them the all clear.

It has, on several occasions, although I'm not aware of any where it was a commanded deployment of reversers in flight. https://en.wikipedia.org/wiki/Lauda_Air_Flight_004 https://en.wikipedia.org/wiki/Lauda_Air_Flight_004 https://en.wikipedia.org/wiki/TAM_Transportes_Aéreos_Regionais_Flight_402 https://en.wikipedia.org/wiki/TAM_Transportes_Aéreos_Regiona...
- avianlyric 5y agoLike I said, zero reasons for using reverse thrusters in the air. Complete loss of air craft if you do.
