SeedyGraphite is used in the batteries which is needed in order to improve the range, the motor is actually a smaller issue but more expensive per amount of power delivered, so its just a cost balancing issue. As for remaining silient i see he does over react sometimes but we should get there in the end...evenually!
As for you,you are talking about rare-earths which we do not produce and you look like you are trying to equate the two which looked like a smear, you are getting your apples and oranges mixed up.
