Much harder to make a secure device that is resistant to getting pwn'd if you can run any code you want. I personally prefer my iPhone to be more secure than to be more open.
Buy a more open phone if you want one, but stop trying to use legal means to force the software on my phone to be worse for my use-case just because you want to have your cake and eat it too.
Closed devices are secure, yes. Apps can use pinned https certs. Apple signs the binary. This ensures that when your personal data is exfiltrated, it will go undetected by malicious third parties such as yourself.
Nobody said that...
You can keep your device enslaved to Apple all you want. You don't have to use the administrator permissions on Windows if you don't want them. Some of us do want freedom
You've got it completely backwards that having the option to control your hardware means you, as an individual, are impacted by anything at all if you don't want to administrate your own device
Once you decide to trade your liberty for security, it becomes the norm and then no one has liberty.
