Every EV is "artificially slower" than it could be and the response to driver inputs is a totally arbitrary design decision.
Tesla Model S Performance with its 0-60 under 3 seconds can still accelerate and drive very slowly and smoothly if the driver chooses to do so, while Mazda with artificially "slowed" acceleration can never go fast. At the end of the day, the car with more artificial limitations gives you less options and is inherently less safe.
That said, I can imagine some people may want a familiar driving experience, although it would make sense to make that a configurable option, e.g. 'sport mode' vs 'comfort mode'.
This type of power curve would also lead to increased wear on a some pretty expensive drivetrain components, so either the manufacturer has to greatly increase vehicle cost to cover for more resilient parts, or sell something that will tank the public's perception of the reliability of their brand.
Aftermarket pure software tunes can unlock some ridiculous amounts of horsepower and torque on modern cars, but expect your axles, brakes, suspension, or transmission components to need replacement much more frequently.
An ICE does require more air and fuel for acceleration as does an EV's motor use higher currents as the pedal is depressed, that is true. The nice thing about EVs is that you get aboout twice as powerful performance for your money.
TL;DR: I agree with your statement that all EVs are artifically slowed, just adding that all vehicles including ICEs are also artificially slowed in order to behave a certain way on normal roads.
