If you want to use a smartphone, you basically get to decide who you trust more with the device that holds a lot of your digital life: Apple or Google. I know how Apple makes its money, and I know how Google makes its money. This makes the decision very, very easy.
Your argument basically is "yeah, I know one of these companies is already actively exploiting my data for profit and the other isn't, but hypothetically they might some day in the future so that means they're indistinguishable from each other today". Which makes it close to impossible to treat you as arguing honestly and in good faith.
