That’s not necessarily true - realistically not using google or Facebook, for the average, non-tech person, is in many ways up there with moving from say, France to Germany (I chose the EU to make a specific point about ease of movement) in terms of difficulty.
Also, at least democracies have formal mechanisms for holding governments accountable, even if these mechanisms are often corrupted or flawed.
Living in a democracy means you have options beyond “voting with your feet”.
