USSR official propaganda commonly used “we” to mean the country, and I've seen elderly people doing so as well.

Born in 1992, however, I never heard anyone in their twenties using it this way.

Folks of my age, obviously besides the football fans and clueless army guys, cringe when they see “we” being used to mean USSR or Russia, perhaps as a kind of allergic reaction to the brainwashing that their parents' generation experienced.
