You’re missing the point. You just came up with a reason to support your conclusion. This isn’t data. It isn’t even really a theory, it’s just an untested hypothesis. Most anyone can do this with any claim, which I demonstrated by doing it for mine as well. Which of ours is more valid? Both sound like reasonable hypotheses, at least IMO.
I don't disagree with calling it a hypothesis. I said theory, which is synonymous in normal language. It's what I had.
It's also true that people hate Musk, and so I need to take what they say about Tesla with a grain of salt. I'm pretty sure I had heard this back when people still thought he was a savior of some sort, but as others have pointed out the cars themselves have changed.
Price is a concern, and for myself open-sourceness and repairability are a concern. Unless it's also anti-Musk hype and I'm misinformed, the Tesla ecosystem is a hell of a walled garden.
