That point is often brought up, but it kind of invalid. Because you can't run iOS on your Linux or Windows installation, too. So saying because of that usecase you are switching the OS, is kind of a spite reaction, not based on reason.
As in: "I can't run iOS on my macOS installation, so I am going to use a different OS where I can't run iOS either".
Well, it's less of a feature argument, and more of a "I philosophically don't support using an OS that prevents me from using parts of it, because I oppose losing control over the software my system runs."
I switched from pixel to iPhone in large part because pixel removed the rear fingerprint reader, headphone jack, and a UI shortcut I used multiple times a day. It’s not like the iPhone had those things but now neither did the pixel.
