As much as I'd like to use a Linux phone, it's simply not feasible for almost everybody at the moment.
What do people user their phone for?
- Private conversations
- Banking
- All kind of apps
Linux phones, at the moment, are way behind Android/iOS in terms of security and, since privacy requires security, also in privacy.
Even stock Android has so many more security features, that it's not even close. Verified boot, exploit mitigation, (working) app sandboxing and so on. Not even speaking of specialized projects like GrapheneOS.
Even if the app ecosystem was there and the OS mature, I'd never run my banking through a Linux phone at the moment.
Yes, but in fairness: The same is true for iOS or GrapeneOS, though that's for valid reasons.
