The reason why is because on iPhone, I can only hope and pray for things to get better, which I have been doing for three years; there aren't really any options if you don't like the intentional limitations of the iPhone. With the Pixel phone, I have options
today and indefinitely, regardless of the motivations of Google. Comparing Google's motivations vs Apple's motivations is missing the bigger picture.
It's not a panacea, but it's about as close as they come.
