I would immediately jump ship if I could buy a phone that supports a truly free OS. Instead, I'm stuck with an option between a reasonably-secure, but completely locked-down phone (both hardware and software) with an exorbitant life-long cost and semi-locked-down phones with a pseudo-FOSS OS, whose main business is to my leak personal data for a dozen companies. Honestly, the only reason why Android (and iOS) reign unchallenged is because of their iron grip over the hardware ecosystem.
