You have a rather confused view of the world, and it's making you rather unhappy. You bought a car with software that is intended to be updated. That means it will change. You bought that, but you don't seem to understand what it means. Some things will get better and some will get worse over time. You don't get to choose and you get no control. If you don't like that, then don't buy such a product. I'm quite sure the vast majority of Tesla owners don't care one way or the other. I doubt they could tell you what's different. Observing the complaints you see here tells you little about the wider world. Meanwhile, Tesla is heading towards a world of full self driving. This whole question of what goes on the screen that isn't entertainment will become increasingly irrelevant. That's what they are concentrating on. And me, I'm kind of amazed to be observing the massive amounts of complaints from people saying that yesterday they were driving a car ten times better than any other car out there, but now it's degraded to only 9.99 times better and they sure are angry about it. I just saved spending hundreds of dollars on a dash cam! And the UI differences between the V8 and V9 on the S and X are inconsequential. In fact the UI differences between the 3 and the S are inconsequential. They're good enough. And they're all software so they're going to change, mostly for the better. Get used to it.
