I trust my government to not infringe on my free speech but I don’t trust that another government that doesn’t have good diplomatic relations with mine doesn’t detain me if I happen to fly through one of their airports because of my beliefs. I avoid China and Chinese airlines because I don’t feel like censoring myself on the internet. Luckily China doesn’t have too many allies.
