There are more errors in Wikipedia than in RAVE, I have corrected quite a few, RAVE is correct in this instance but you have clearly never had a flywheel/flex plate assembly in your hands and you obviously, as you say,do not like been corrected.
Why can you not read the drawing? The flex plate is a thin plate mounted on the flywheel ring gear unit centre where it attaches to the crank, to which to torque converter bolts, the flywheel is certainly lighter than on a manual, but it is a fecking cast steel lump that has little or no flex and if you look it even has balancing holes drilled in it. When the flex plate cracks, it is that thin inner disc that gets replaced not the flywheel/ring gear.

This may be a case of differing terminology, you regard the whole assembly as a flex plate. But if you have ever taken one off the crank, the the bit with the ring gear on is a pretty heavy lump with the mass located around the periphery, certainly not as heavy as the flywheel on a manual which also has the clutch assembly adding mass, call that what you may but it has a flywheel effect. The flex plate is the thin disc in the middle to which the torque converter bolts and indeed the torque converter provides additional mass for the flywheel effect.
I agree ; Autos are problems
Sure it's not a "whatyereallycallit"?
