My what a short memory you have. The FAA grounded all DC-10's for a very long time after the engine seperation and crash in chicago.
In the case of the 737 rudder hard overs, a fix was immediately implemented. The aircraft speeds were changed to require flying faster than crossover speed so that a hard over rudder could be overcome by the ailerons. That required adding 10 knots or more to approach speeds.
For those of you who are not into aerodymanics, crossover speed refers to a specific angle of attack. An angle of attack lower than crossover will have the ailerons stronger than the rudder and a greater angle of attack would make the rudder stronger. So to reduce angle of attack you either unload (reduce G) or increase speed. The 737 is now flown faster so that a rudder hardover, while exciting, isn't fatal, like an engine failure or other problem we are trained to deal with.
As to the aloha aircraft, much of ALoha's fleet and several other aircraft of similar vintage were immediately grounded. Others were life limited as a result of the ageing aircraft program that followed the initial grounding. (60000 cycle inspection became too expensive)
So, no it is not a plot against airbus, you are free to keep thinking that however. In the meantime there is another similar accident in Africa from about 2 years ago on the A300/310 that is also unsolved. 2 aircraft out of 400 or so vs 2 out of 3500 737s sure doesn't look favorable for airbus.
But go ahead and falsly scream protectionism if it helps you sleep better.
