I'm not an apple fan. Most of my personal devices run Linux, but I feel essentially trapped on an iPhone. It doesn't seem like there's a truly useful open phone out there. I don't like Apple, and I don't trust them or their ostensibly pro-privacy stance much, but I want as little privacy invasion and as little advertising as possible on my phone, and I think as bad as Apple is, they're still better than a fully Googled version of Android. Unfortunately, a lot of people, myself included, need at least some apps that require either an iPhone or a fully Googled version of android.
I suppose there's always the option to dual-wield and use a Linux or de-googled android phone for daily use and keep a second device around for the apps that won't run there, but that is both a pain I don't expect many people to buy into. I'm just about at the point of going this route for myself, but it does feel more like admitting defeat than anything else.
