We should have the ability to run any code we want on hardware we own

Why isn't there a linux flavor for phones with an app store?

The same reason why linux isn't broadly used on PCs: Lack of hardware support and drivers.

There is Sailfish os Ubuntu Touch, you can run Fedora and Debian rebuilds on phones. I think it is finally getting there & all this Google and Apple bullshit will hopefully make it move faster and be more attractive to people. :)

Yes, PureOS, Mobian, postmarketOS and more.
