In the Russian's culture, you don't pay for software: you get a pirate version (in most case they wouldn't have the cash anyway).
Now, if Putin thinks he can get out of "the free software", that's would indeed just show a complete lack of understanding of the sector... But I don't think it's the case. They more probably will remove a few backdoors, anyway add their own with maybe a beacon, and change the wallpaper: after his recent "management" of the Russian future, I don't think indeed they still have the means to to go any further.
