SailfishOS has very poor privacy and atrocious security. The portions of the OS they make themselves are largely closed source. It's a massive regression from the privacy and especially security of the Android Open Source Project even without the major GrapheneOS improvements. It's strange to see it marketed based on using open source code as the foundation for building it when they don't open source a huge portion of their own code. Android Open Source Project is a complete OS that's open source. SailfishOS user interface and application layer is largely closed source. SailfishOS doesn't provide anything close to bare minimum privacy and security patches. It lacks many important standard privacy and security protections. Bringing a desktop software stack with much worse privacy and security to mobile but while having much worse updates than a lot of Android OEMs do for similarly priced devices is hardly progress. Their Android compatibility layer is insecure and not a safe way to run Android apps. It also has very poor compatibility in practice anyway. Jolla worked with the Russian government from 2015 through 2023 and Russia took a large share of the ownership in the company. In 2023, they used a sketchy bankruptcy restructuring to drop Russian ownership of the company. Regardless, they had no problem working with them before. Russia has a state-owned fork of SailfishOS called AuroraOS. It isn't possible for others to do the same since it's not open source. European values apparently mean closely working with Putin for 8 years after initial the invasion of Ukraine. It's a strange way to market it based on their choices and history. It isn't what they claim it is in their marketing and we strongly recommend against using it. They've chosen to very actively mislead people about GrapheneOS because they feel very threatened by it so we have no problem saying what we think about it. We used to keep quiet since it's simply not very relevant.
