I don't think you are using two points that are similar enough.
If Australia bans encryption, you as a consumer who resides in Australia has a high switching cost (moving, new job, residence, etc.) and thus the consumer loses out.
If Apple starts to use that power badly... you can switch to a number of competitor feature phones with largely the same feature and app capabilities (Android being the most obvious)
In a market with 2+ competitors and where its low switching costs (moving contacts is quite easy these days, not a lot of deep 2-year contracts for phones/providers) this point doesn't hold true
The points are not supposed to be similar... you're missing the part of the parent's argument where one is used as a tool to enforce the other, when otherwise it would be difficult/impossible to enforce.
There is only one real competitor: Android. Google would very much like to have the same degree of control that Apple does over their ecosystem, but they're holding back for now so that they can point to Apple as being worse when the congressional inquiries heat up.
Feature phones are not real competitors to smartphones.
I'd argue there is a third competitor in the form of Huawei/Xiaomi. Despite fears of spying by the Chinese, which might be justified, their phones tend to have better prices all the way to the ultra market, and due to the fact that they want to allow you to sideload GsmCore and Play Services, will never be locked down.

It depends, network are effects are strong on Apple (iMessage) and maybe you already bought tons of apps and software that you can't transfer to Android or Windows.
"you can switch to a number of competitor feature phones with largely the same feature and app capabilities"
How much does that cost? How does it work if the apps you rely on are iOS only? How do I transfer my app and subscription purchases to my new Android phone?
