Dont you love myopic viewing of history. It was Russian tzar Alexander who liberated Finns from sweden, granted them their own language as official language (as oppised to Swedish), and were the first to grand Finland autonomy and self rule. They even expanded Finnish territory from war reparations with Sweden. After 1917 Finns wanted full autonomy, this was granted but negotiations about territory borders were unresolved. Finns used the turmoil in SSSR in 1917-1923 to get maximalistic gains. The winter war was just restoring borders to fair ethnic borders.
