Look, we can get into the nitty gritty details, but if we're going to have this debate, you have to do some basic research online to see how Amazon is currently hurting the Ebook market, or how DRM is actually affecting markets and consumer choice at this moment. I will still assume you're coming into this from an honest perspective of inquiry, but you have to put in a little bit of work here, I'm not going to summarize the entire history of US antitrust for you.
It's going to be very difficult to have a productive conversation if you don't understand how device/vendor lock-in works. Do you really not understand how holding people's purchased libraries captive prevents those people from moving to new devices or ecosystems? Do you really, honestly believe that a superior book ecosystem of any kind could spring up and Kindle owners would just say, "well fine, I'll throw away $200 of purchased Ebooks! It's no big deal." You don't think it affects consumer's book purchasing decisions at all that it's impossible to put Kobo books onto a Kindle or Amazon books onto a Kobo device without breaking a federal law?
Please do some basic research about how DRM and platform lock-in works on Apple/Amazon devices. I heavily recommend reading some of Cory Doctorow's work, or looking at the history of how the DMCA/CFAA has been used to shut down market competitors via legal means instead of via competition, or into how Apple increases lock-in with their current product direction on things like SSO/subscriptions, credit card offerings, and proprietary device standards that competing companies are not able to interop with.
Apple's current product strategy is to increasingly make it so that anyone who wants to buy a different phone must also throw away a substantial amount of sunk cost into app purchases, hardware that isn't allowed to work as well on other devices, social status (incoming Android messages are literally labeled differently in iOS), they may even be forced to cancel their current credit card. This is a really textbook example of how vendor lock-in works, you can find more detailed information online if it's something that you're actually curious about.

The way I see it, there are two fundamental problems I have with your point of view.
A) I don't believe that customers magically become stupid or smart based on whether they're holding a smartphone or a credit card. I believe that people's decision making processes when using devices and purchasing devices are the same.
B) I believe that if people actually want to do something, you (usually) shouldn't have to force them to do it. If people genuinely wanted to be in Apple's walled garden, Apple wouldn't need to lock the garden from the inside. It's one thing to argue that people are too stupid to make their own security decisions. It's one thing to argue that people are too stupid to prioritize long-term market effects. But it's ridiculous to argue that people want to be in a walled garden when literally every single opportunity you give them to turn it off or install apps from outside of it, they immediately do so.
That is not the behavior of people who are happy with where they are. I don't know how to do my own plumbing. The reason you can tell that I'm happy to let other people make my plumbing decisions is because I haven't yet taken a hacksaw to my pipes.
If every single opportunity to take apart my toilet I did so, you might reasonably conclude that I did want to do my own plumbing, however misguided my beliefs about my own abilities were. And if having a checkbox in settings labeled, "warning, you are definitely going to be infected by malware" doesn't prevent people from turning off security safeguards, you might reasonably conclude that they do want to manage their own security, however misguided their beliefs about their own abilities are.

> I know because they switch to a more secure & locked down platform wherever they can.
This is a wildly simplistic model of how customer behavior actually works. There is a nontrivial percentage of Apple customers who switch to iOS because they're worried about their SMS message bubbles getting colored green. You can't seriously argue that those people are making a security decision.
And in any case, this is all kind of moot because if you want to pretend the market perfectly reflects majority preferences, then people didn't flee Android en-mass. Apple holds a market majority on paid app downloads, but they don't hold a majority of market share on actual devices. The majority of users switched to Android.
Of course, they probably switched to Android in no small part because of large price differences, not because of "openness", but if I'm correctly understanding your worldview it seems like we're not allowed to acknowledge things like that, we have to assume it was an ideological decision because the majority of the world wanted sideloading.
