The negativity is from being wasteful. I expect to see Tesla criticized for this. How can you have a mission of changing the world and fighting climate change, etc etc
and then turn around and spend all of this time, energy, and by the way a carbon footprint, to produce a car that is just a plaything for a rich guy?
The stone age didn't end due to a lack of stones. It's very hard to change the world by making people feel guilty.
This car does two or three things for Tesla.
It's the final nail in the "EVs are slow, ugly, short ranged over size golf carts" coffin, helping EVs seem cool and exciting and getting them reviews and articles and mind space for folks that would never buy a car that expensive, but wouldn't have considered a Model 3 before they heard about this car - a classic halo car.
It supports their mission of moving the industry to sustainable transport by forcing all the exotic car makers to up their game - the performance and price point are way outside of their normal realm, and they will have to make better cars or cheaper cars to compete - and the most likely way to make cars that can compete is to electrify, a trend you already see across the top end (Porsche 918, LaFerrarl, etc.)
It's arguably also a stealth financing round - this month, they'll make $250 million from the founder's reservations alone that they don't have to pay back with deliveries for three years.
