I am one of those that bought a model 3 in 2018 but did not buy EAP and FSD. EAP+FSD for $5k was very tempting but I decided to pass as I did not consider it to be useful for my particular situation. I like driving the car and I do not take long trips or get stuck in traffic during commute. I plan to keep the car for a long time so resale was not a factor either. So the option was not worth it to me personally. I would probably use the money to put down an order for a Y instead.This is an entirely different situation. I am discussing paying for software and the promises made. I have not said a word about the M3 price drop, or the value I paid for my Model S vs what you get today. But if that is how you choose to move forward with this conversation I can't say or do much about it.
If you look at this from Tesla perspective they offered this deal as a way to get some revenue from buyers like me or buyers who did not get FSD. A different way to look at this would be through an analogy of buying an airline ticket. If you buy it early you are guaranteed a decent price and a confirmed seat. If you wait until the last minute the price will go up in most cases when there is enough demand and you will pay more. If there isn't enough demand the airline will drop the price to fill the empty seats rather than keep the ticket price the same and fly a partially filled plane at a loss. So people who buy in at the reduced price may be lucky but they were never guaranteed a lower price or a seat compared to some body who bought a ticket early. In this case Tesla had unlimited capacity in that they could sell to as many buyers as they could find to realize some revenue with out an additional cost to them. That is until people who paid more for this started complaining and Tesla had to revert the prices.
