As far as I know, from February 2022, the public sector is actively switching to local operating systems (AltLinux, Astra, ROSA, and something else) with a Linux kernel. Russian accounting systems, office packages, engineering design systems, etc. have long been written for Linux, and now they are finally becoming popular, whereas before they had to “pick up crumbs from the table” after Western multinationals.
Home users are also slowly getting involved in Linux OS assimilation, but the inertia is huge and most of them are too lazy to change anything. Just gradually come a new generation of users who are interested in dealing with something new and they notice that not Windows unified can be put on your computer.
Games still pull people to the old, but Stim helps to get away from this archaic.
In short, as Max Planck said, new knowledge (paradigms) comes when the carriers of old knowledge leave.

There is also a Russian version of BSD - Ulyanovsk BSD , but it seems to be poorly developed. Unfortunately, I can no longer access this site, because my current Ukrainian provider blocks access even through VPN.-(
