No, I am simply saying that Airbus are not some tin-pot back yard chancers, that's all. Some on this thread are implying that Airbus have made a mistake or a cheap fix, but that won't be the reason.
Airbus do employ the best designers, engineers and test pilots - as Boeing used to do back in the day - and they wouldn't use a single physical rocker without good reason. The A300 also had a pair of FBW spoilers, so Airbus were designing and producing FBW on that airframe too.

Correct. But the pilot can - and will - detect any mechanical issues with the rocker - whether it is mechanically sticky, or sticking, or graunching, or not actuating both switches underneath.
