So this came after the Bolshevik-Makhnovist conflict, where “After Nykyfor Hryhoriv mutinied against the Bolsheviks, tensions between the two factions culminated with the Makhnovists being declared outlaws and Makhno resigning his command within the Red Army.” So they were consistently breaking agreements they’d made, refused to surrender and reintegrate with the Red Army to fight the greater Polish-Soviet war, and were thus declared outlaws. Not a great look imo.
