I gave another try to check for any open source update, it is not and added more mess. See here https://docs.sailfishos.org/Develop/Open_Source/ :

“As described in the architecture documentation Sailfish OS consists of a variety of components, some of which are proprietary and closed source (such as some hardware-specific kernel modules, or other software licensed under commercial terms), and most of which are open source.”

They removed open source components from “architecture documentation”

The os is impossible to build and test like linux despite of being based on open source project like linux, wayland, QT, etc.

SailfishOS is closer source than Android. Android you can compile and degoogle it.

Here what I found:

As of late 2023, Jolla, the Finnish mobile software company behind the Sailfish OS, was acquired by its former management team. They bought from Rostelcom. So they sold to Rostelecom and original management “bought” back. The original Jolla Oy company filed for bankruptcy in 2024, but the business operations and employees were successfully transferred to this new management-owned entity in late 2023.

1. Positive cashflow can be made in a honest way if they really wanted to make a difference. By now yhis project would boom and overtake apple and android, not the case. They even sold to Rostelecom and Yandex. 2. New owners? More open? Any evidence? 3. Time doesn’t fade facts.
