For me it's a trust issue.

I don't trust that Apple (or Google) won't use their software against my interests on a device I own and have with me at all times.

With a non-apple phone I can ensure that my interests are preserved by vetting different software options.

Ditto, I had a therapist recommend practiceing mindfulness with apps like medito or mindfulness coach.

That's a cool dog

That's a weird way to say 54% of the average American's emissions are caused by cars
