I don't think that there was
I don't think that there was anything particularly wrong with the Cybertruck unveiling. It is just that Tesla's design choices are polarizing. Similarly, the Rivian's nose looks awkward to me. Tesla short sellers are itching to use any excuse to make a profit off of anything that they can twist into some notion of failure. I am sure that some TSLA stockholders wanted to see the Tesla truck released as a direct competitor to the popular and profitable F150 and Silverado pickup trucks, just in EV form. And those folks were disappointed to see the wild looking Cybertruck. Since very little about the Cybertruck (other than looking like it was out of Blade Runner) was known. As a truck, the Cybertruck seems to be pretty compelling fundamentally in terms of features, price, and capabilities. The styling is polarizing, but realistically Tesla's truck was clearly never aimed at the ordinary, mainstream buyers anyway. Like Rivian, Tesla only needs to pick up 2-3% of the truck market to be profitable, and I think that this truck is going to appeal to a great many buyers who want something completely different than the rest of the population.
