It's not like the A330 is short or metal parts to strike either.
It doesn't have to be metal to get hit. Lightning hits lots of non-metalic things like trees. It's a matter of electrical potential. Electrical charges will flow (They're called lightning) from a region of high potential to low potential, regardless of the material. With enough potential difference to overcome the resistance of the medium in the middle, charges will flow.
How many other Airbus aircraft have ever had difficulties following a lightning strike? How many have had problems with turbulence? Both are generally non-events.
There is a first time for everything. Think about BA038.
