I think they know exactly what they are doing with pricing. They are playing with the price to understand how elastic the demand is for the car and the timing of all the price adjustments further supports that they are lowering prices specifically to increase sales/revenue. There really isn't any other good reason to reduce a price other than to motivate sales, frankly, or you are just throwing away money.
People like to say that Tesla is "passing on savings to the customer from production improvements" but think about that for a second, why would a corporation want to purposely reduce their revenue per product? Answer: elastic demand. Elon has even said as much by saying things like "we have unlimited demand, it's just the price that holds us back".
I agree that reducing the price of the car itself is NOT a lie since no where on the website did it say "Will be +3K in 3 months". FSD, on the other hand, specifically said that it would cost more post-delivery in writing with no ambiguity.
Saying its "just how they do things" implies there is no logic or reason to their decisions which is antithetical to everything Elon stands for (physics, first principles etc.). They weighed the pros and cons and decided revenue was worth more and to be honest, i would probably have done the same thing if i was at Tesla - but it sucks as a customer.
Price we pay to help Tesla survive until they are more mainstream and i'm OK with that, but it sucks.
