No, AuroraOS is the Russian fork of Sailfish.
Sailfish was in kahoots with the developers of Aurora, but they split ties when Putin spat the dummy at Ukraine.
Personally I wouldn’t buy a Jolla C2, but if you can get your hands on an Xperia 10 (working features vary by version, my 10 IV is not too bad but the 10 III is more polished) or a device supported by one of the better community ports, it’s worth a go.
I used to think so too, but my pi-hole just died the other week after four years of uptime. Couldn’t work it out, finally pulled the SD card out to reinstall the OS and found my laptop wouldn’t recognise it.
Made me glad I don’t run my mailserver on a Pi anymore!
