Ukrainians in Crimea and other annexed territories [that are not close to the front lines] have more or less normal life now. They can continue living where they live, or they can at any moment return to Ukraine, nobody is holding them hostage, they are free!
On the other hand, Ukrainians who failed to escape Ukraine don’t really have a choice other live in fear that today might be the day they (or their family) get kidnapped and sent to the army, or try to escape and get caught by “heroes” of the border patrol who carefully watch that nobody escape the meat grinder (unless they give them a hefty bribe).
