But, as a consumer, things like a moving price target; TWO CHANGES in around SIX WEEKS is too much.
Remember back in the day; around 2010ish, Patek Philippe prices were constantly increasing? That was annoying. But even then, they didn't change within SIX WEEKS!
Market studies in the past has shown that people who want to buy red cars are fairly inflexible about their demand for red cars. And thus, car manufacturers have realized this and have started to offer more red cars in the USA market; these cars are often at higher cost (in the price of the paint, or these cars are loaded with more options). But even then, I've never heard of a car manufacturer change the price of red paint three times in six weeks.
Imagine you go to the store to buy toilet paper. You see that they only have the bulk rolls of 36 rolls per pack for $5. You think, maybe I'll hold off, I've still got two weeks supply worth, I'll come back when I have about a week's worth. The next day you come back, the price has increased from $5 to $7.50. Then another day later it's gone up to $10. It's a moving price target. Is it unethical? No. Unless they raised the price due to a storm, that would be illegal since you can't price gouge in a time of disaster in most states/territories/provinces in the USA.
It's just not cool, and it's not right. It might not be illegal, it might not even be unethical, but it's something that sure is embarrassing that Tesla would have such pricing instability. I can imagine they will de-content the car and add it back as expensive options in the future to maintain that $35K price target.

In your case, I'm glad that you didn't buy another car. From what I hear about your car collection, it seems the LAST THING YOU NEED is another machine in your driveway! You don't seem to be an especially high mileage driver, and you seem to have several cars already. I don't know about you, but the insurance costs of so many cars would scare me away.
I'm glad you didn't buy the car and I'm glad you didn't let those guys win!
Now I'm wondering, would I be happy with a BMW i3... A used BMW i3 is quite affordable these days. How are they to drive on the freeway, is the steering ratio too quick? Car might be a bit twitchy. Is the range too short at highway speeds (I hear range drops to like 62-65 miles at a 75 mph cruise speed). And when the wind blows, does the car feel unstable? And how long is that BMW Flexible Mobility program going to last? So many questions and concerns!
Tell me more about resin prices increasing. I need to paint my home too, come to think of it; I wonder if exterior house paint has increased much in the past several months.
