Your data is YOUR data!
An iPhone or an Android smartphone collects several megabytes of your personal data every day to Google Servers, even when it is inactive.
Murena smartphones have been designed to offer a different approach to users who care about privacy and data-hungry handsets.
Those smartphones are running the open-source “/e/OS” operating system, which is fully “deGoogled”: by default it doesn’t send any data to Google and it’s been designed to offer a great and natural user experience.
/e/OS is paired with carefully selected applications. They form a privacy-enabled internal system for your Murena smartphone. And it’s not just claims: open-source means auditable privacy.

I think you're confusing rooting with unlocking the bootloader. These most definitely have the bootloader unlocked, or at least, it had to be unlocked to replace the OS (sometimes it can be re-locked after), but they aren't necessarily rooted.
Bootloader unlocking is officially supported by many manufacturers (though your warranty is voided), and allows modifying the OS, which might be rooting, or completely replacing the OS (and the new OS might not be rooted).
Rooting, instead, just means becoming "root" (superuser, admin) on the device, which allows (almost) complete control over it.
