Some are more "hackable" than an iPhone, but only in some strange symbolic way, since once you de-googled android is somehow more user-hostile than iOS and completely unhackable in practice (in the sense that I can't make it do what I want and also be usable as a daily driver that lets me do stuff like pay for stuff, use public transit, charge my car, park, or take an uber/lyft).
I'm a happy owner of a pine book pro, and a pc engines router; I get it. However, I don't think there are any viable Linux laptops or phones that compare favorably to the linux laptop + phone I had a decade ago.
"(in the sense that I can't make it do what I want and also be usable as a daily driver that lets me do stuff like pay for stuff, use public transit, charge my car, park, or take an uber/lyft)."
So either the hardware you bought isn't letting you do what you want with it (this includes iPhone too!) Or you become a better hacker and get it to work yourself.
