Country X passes a law that says search engines cannot return politics results.
If I stay in country X and filter out politics then the people in country X end up with no politics search and the best search in the world in all the other categories.
If I decide to not operate in X then the people there use some second rate search engine that obeys X's law. The people of X still end up with no politics search and they end up with second rate search in all the other categories.
How does my not operating in X help the people of X?
