It’s an oversimplification to position them as opposites. Airbus uses higher level contol, more a flight path than a control surface movement. But pilots can revert to direct law and have full contol authority when required. Boeing aims for a more traditional control feel, you move control surfaces instead of commanding an outcome. But with layers of substantial augmentation on top of it, up to and including for example the 737 MAX MCAS.
In practice, both approaches blend automation and pilot authority rather than strict philosophical extremes. And the practical difference at the controls is also not as extreme as some people think it is.
There is no oversimplifying happening here. There is no documented procedure to switch to direct law in an Airbus.
In fact, the only way to get into direct law on a fully functional plane is to start pulling circuit breakers for the (redundant) flight computers and inertial reference units.
