Of course, ICE powertrains have lots of moving parts, but the comparison that EV cars are simple is just not an accurate representation of EV cars.

There are fewer moving parts, I agree. The architecture itself is simpler too, I agree. But the individual components are still massively complex and expensive. High density Lithion-ion is very complex, and also requires a number of supplementary systems to manage power, heat, cooling and monitor the array.

You could make the same argument about the exotic metallurgy used in ICE components. Just like with an ICE subsystem, most of those subsystems you mentioned aren't trade secrets and have far greater operating tolerances than in an ICE.
