I don't believe this is true or even a consideration for the majority of users.
Proof of that, specifically.
In economics, vendor lock-in, also known as proprietary lock-in or customer lock-in, makes a customer dependent on a vendor for products and services, unable to use another vendor without substantial switching costs. Lock-in costs that create barriers to market entry may result in antitrust action against a monopoly.
It’s of marginal importance to me, but the ability to install virtually anything on the App Store reasonably confident it’s not going to break my primary communication device or exfiltrate my data (without my permission) etc etc is of far more importance.
I rely on my phone very heavily and the fact that it reliably Just Fucking Works is much much more important than being able to — for example — run Firefox on it
I can stop programs from running on startup and can force them to be killed instantly when they are closed so they aren't running in the background.
I can also write and run my own programs without having to own Apple hardware and can distribute them without paying $99.
For me, it really is a question of privacy vs walled garden and I choose to give up some privacy.
> Walled garden is just an anti-marketing term
Which is what I was arguing with. For me, it's a big anti feature, big enough to always choose Android over iOS. I won an iPhone at a company xmas raffle and gave it to my mother rather than keeping it. She also doesn't care about those things, so it's much better fit for her.
> you just fight with your phone’s bad habits.
No, I make my phone do what I want it to do. You accept that your phone does what Apple wants it to do. I don't like being forced to change my habits based on some 3rd parties whim.
My issue isn't that you prefer not dealing with these things, it's that you entirely dimiss the notion that someone does and that a "walled garden is just an anti-marketing term".
