It's an open source project that nobody is getting rich off of, so voluntarily cutting ties with the Russian market doesn't present the sort of moral dilemma that TAM-obsessed, locked-down, for-profit OSes worry about.
AuroraOS was very much a commercial errand by Jolla Oy, not some open source volunteers hacking on it in their free time.

Not fully open-source though, as far as i understood it some of the important GUI, android compat bits are propreity and thus need licensing so no easy way to function without them as opposed to the linux kernel.So i think they are in a very similar postion to android techstack wise , its just their biz model requires direct licensing rather than the ad subsidised android. On another note i think this was the rationale for risc-v moving to europe (avoid the geopolitical) so anyone regardless can utilize its designs.
