Let me put it this way. In this case, specifically, what you're claiming is pretty outrageous and, if true, sounds like something I should take more seriously too. If you can give me examples of Tesla abusing users' trust and operating in a way that is not in accordance with their privacy policy, user consent, and/or general understanding of techno-decency, then please surface the evidence to support your claims so I can consider your argument more seriously. Otherwise what you're claiming does not align with my experience owning a Tesla and my knowledge about how they're designed and engineered.
The pragmatic in me understands that there is always a risk that a future software update will change the behavior of a product in a way that is not in my interests. That is a risk I take by using any software product and something that responsible people keep an eye on, agreed. I'm just not going to categorically avoid software that can be updated out of fear that it could start spying on me. If it starts spying on me without my consent, good bye.
I also understand that we may even have different tolerances for living with connected hardware and software. If you're the type of person that compiles their own firmware and updates their own devices offline after personally vetting the software, I'd buy your concern about trust a little more too. But honestly it just sounds more like you're saying "yuck Tesla, I wouldn't trust them to build a respectful product", while ignoring the fact that you're likely posting this from a smartphone, if you know what I mean.
