The OS was 'licensed' to a Russian distro as AuroraOS , not sold.Its still belongs the Finnish company.Note , that was their biggest install base and revenue source they cut themselves off from.

Jolla had ROS Telecom as an investor since 2015, which might have held a majority.

A few years ago the Russina investors were unresponsive. The Finnish people from Jolla set up a new company and had all property moved to that new company through a court case. It's not the same company as before.
