No one said that Tesla could "never" offer a Model 3 for $35k. There was a lot of chatter about them not being able to do so on anywhere close to the timeline Tesla claimed they would, and some of that came from Tesla itself. As recently as 2018 Elon Musk said that offering the Model 3 for $35k would bankrupt the company due to the non-existent profit margins due to the unit economics.

And while we're on that subject: Tesla also announced that in order to build the Model 3 for $35k they would need to fire the entire sales team and switch to online orders only, and eliminate referrals. So it seems that even Tesla still doesn't think that they can offer a $35k Model 3 profitably based on their existing unit economics.

And now it's done, the 35k model 3 is delivered, and people are focused on what, missed deadlines they self-imposed in the past? Is that really the most important issue here?

For investors, a company that perpetually misses deadlines is a serious, real-world problem indicative of poor planning, leadership, and management. It's one thing to miss the occasional deadline by a few days or weeks. It's another thing to miss every deadline announced, by months each time. At some point, the "self-imposed" publicly announced deadlines are just fraudulent statements intended to induce investors to buy shares of the company. CEOs have been criminally prosecuted for that in the past...another former SV darling is being prosecuted for that right now...
