@kev Probably the Apple angle. In my experience, there are two groups within the FOSS community when it comes to Apple.
1. Views Apple as an improvement to Google. Apple doesn't collect the data about you that Google does, so they're a step in the right direction.
2. Views Apple as worse than Google. Google allows you to customize your phone and switch out just about everything about it. Apple barely lets you sort your icons.
When you ditch Google for Apple, you're riling up one of those.
